emulators/mupen64plus-core: fix build with clang and lld 19
lld 19 has become more strict about 32-bit relocations that require PIC,
resulting in link errors when building emulators/mupen64plus-core:
LD libmupen64plus.so.2.0.0 ld: error: relocation R_386_32 cannot be used against symbol '__gxx_personality_v0'; recompile with -fPIC >>> defined in /usr/lib/libcxxrt.so >>> referenced by oglft_c.cpp >>> _obj/osd/oglft_c.o:(.eh_frame+0xFA63) ld: error: relocation R_386_32 cannot be used against local symbol; recompile with -fPIC >>> defined in _obj/osd/oglft_c.o >>> referenced by oglft_c.cpp >>> _obj/osd/oglft_c.o:(.eh_frame+0xFA81) ld: error: relocation R_386_32 cannot be used against local symbol; recompile with -fPIC >>> defined in _obj/osd/oglft_c.o >>> referenced by oglft_c.cpp >>> _obj/osd/oglft_c.o:(.eh_frame+0xFAB1) ld: error: relocation R_386_32 cannot be used against local symbol; recompile with -fPIC >>> defined in _obj/osd/oglft_c.o >>> referenced by oglft_c.cpp >>> _obj/osd/oglft_c.o:(.eh_frame+0xFAE1) [...more of these...]
Make it compile with -fPIC even on i386, by adjusting the PIC make
variable. This also removes the need to use -Wl,-znotext as a workaround.
