perf: Normalize gcc parameter when generating arch errno table
The $(CC) passed to arch_errno_names.sh may include a series of parameters
along with gcc itself. To avoid overwriting the following parameters of
arch_errno_names.sh and break the build like below, we just pick up the
first word of the $(CC).
find: unknown predicate `-m64/arch'
x86_64-wrs-linux-gcc: warning: '-x c' after last input file has no effect
x86_64-wrs-linux-gcc: error: unrecognized command line option '-m64/include/uapi/asm-generic/errno.h'
x86_64-wrs-linux-gcc: fatal error: no input files
