From: Antonio Terceiro Date: Wed, 24 Feb 2021 13:00:46 +0000 (-0300) Subject: perf build: Fix ccache usage in $(CC) when generating arch errno table X-Git-Tag: v5.10.25~238 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=640492cf1732a9f97b062c3eec2c5ee37f73dada;p=platform%2Fkernel%2Flinux-rpi.git perf build: Fix ccache usage in $(CC) when generating arch errno table commit dacfc08dcafa7d443ab339592999e37bbb8a3ef0 upstream. This was introduced by commit e4ffd066ff440a57 ("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.
