All non-MIPS arches I've tried compile OK with that flag - but MIPS
dies when trying to compile lib/libc/mcount.c with PIC:
/tmp/ccM2AZVL.s: Assembler messages:
/tmp/ccM2AZVL.s:9: Warning: No .cprestore pseudo-op used in PIC code
/tmp/ccM2AZVL.s:219: Error: 1 warnings, treating warnings as errors
This comes from src/sys/arch/mips/include/profile.h and the MCOUNT
and _PROF_CPLOAD macros:
# define _PROF_CPLOAD ""
# define _PROF_CPLOAD ".cpload $25;"
This test should perhaps include something testing for PIC or not.
