Subject: Respect $(CROSS_COMPILE) when $(CC) is the default
X-Git-Tag: mdadm-4.2-rc1~77
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=aced6fc9542077a69b00d05bc9cd66c12fc34950;p=thirdparty%2Fmdadm.git

Respect $(CROSS_COMPILE) when $(CC) is the default

Commit 1180ed5 told make to only respect $(CROSS_COMPILE) when $(CC)
was unset. But that will never be the case, as make provides
a default value for $(CC). Change this logic to respect $(CROSS_COMPILE)
when $(CC) is the default. Patch originally by Helmet Grohne.

Fixes: 1180ed5 ("Makefile: make the CC definition conditional")
