Subject: [RHEL7.9 PATCH 53/71] 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")
