Antonio Terceiro 640492cf17 perf build: Fix ccache usage in $(CC) when generating arch errno table
commit dacfc08dcafa7d443ab339592999e37bbb8a3ef0 upstream.

This was introduced by commit e4ffd066ff ("perf: Normalize gcc
parameter when generating arch errno table").

Assuming the first word of $(CC) is the actual compiler breaks usage
like CC="ccache gcc": the script ends up calling ccache directly with
gcc arguments, what fails. Instead of getting the first word, just
remove from $(CC) any word that starts with a "-". This maintains the
spirit of the original patch, while not breaking ccache users.

Fixes: e4ffd066ff ("perf: Normalize gcc parameter when generating arch errno table")
