Measured on a PS5 (firmware 13.60): sceSysmoduleIsLoaded,
sceSysmoduleLoadModule and sceSysmoduleUnloadModule with id 0, and the
Internal and InternalWithArg calls with id 0 or 0x80000000, return
0x805A1000 and leave the WithArg result untouched. They threw.

Drop the retry on <name>.prx after libs/<name>.prx fails. The test now
runs from its own directory holding libs/libSceFiber.prx, copied from
the libSceFiber output, so the single path resolves in the test too.

Link libc, configure Windows unwinding for the test so its runtime_error
checks are caught, and run it from libSceFiber's output directory so
openHostModule finds the unpatched libSceFiber.prx next to the modules the
test already loads.

Return a host module handle for a loaded sysmodule id so callers can
sceKernelDlsym after sceSysmoduleLoadModule. Unknown or null inputs
throw like neighbouring internal load paths; unloaded ids return
0x805A1001. Unblocks Prospero Win past NID D8cuU4d72xM at load.

Covers code, stack and an anonymous page, and an unmapped address. On Linux the test runs again with APS5_NO_PROCMAP_QUERY so the line scan stays covered.
It carried its own copy of the /proc/self/maps line scan and is called on the same Unity stack walks as sceKernelGetModuleInfoForUnwind. It now uses the shared HostMapping lookup.
sceSysmoduleIsLoaded returned 0x80A90002 and the unload calls 0x80A90003
for a module that is not loaded. Neither value exists in the SDK: the
sysmodule facility is 0x5A and the error is 0x805A1001, which titles
compare against (GTA V PPSA04263: cmp eax,0x805a1001 after IsLoaded) to
decide whether to load and initialise the module themselves. Return that
value from all three places and cover it in guest_sysmodule.

Every library CMakeLists.txt ended with the same block removing -static,
-static-libgcc and -static-libstdc++ from CMAKE_EXE_LINKER_FLAGS on MinGW,
because core/libs/CMakeLists.txt only removed them after adding the library
directories. Remove them before the libc and library directories are added
so each directory inherits the stripped flags, and drop the 52 copies.

Two exports were missing. System modules are linked statically, so load and unload are
reference counts over the known module table, exactly like the existing
sceSysmoduleLoadModuleInternalWithArg and sceSysmoduleUnloadModule:
- sceSysmoduleLoadModuleInternal(uint32_t) -> increments the module's load count, returns 0
- sceSysmoduleUnloadModuleInternal(uint32_t) -> decrements it, or 0x80A90003 when the module
was not loaded
Unknown or zero ids throw, like the sibling internal loader. Adds a CMakeLists.txt so the
library can carry its guest test. Signatures follow the public OpenOrbis SDK headers.
New test core/libs/tests/GuestSysmodule.cpp loads a module twice, unloads it twice and checks
the not-loaded error on a third unload; it fails without the change (the symbols are
undefined) and passes with it.
sceSysmoduleLoadModule and sceSysmoduleIsLoaded already accept ids the
project does not know and log them; unloading such an id threw, so a title
that loads and later unloads an unknown module aborted at the unload.

libSceSysmodule/Export.cpp parsed /proc/self/maps device major/minor
numbers into signed int with a %x format, which is undefined behaviour
per the C standard even though it happened to work on this target;
switched to unsigned int to match the format specifier.
NidPatcherUtils.hpp's StripNidPostfix built a truncated copy with
substr(0, n) where the prefix is already the string itself; resize(n)
does the same truncation without the extra allocation and copy.
