build.sh: Fix the behavior of specifying CC
Update the behavior of specifying CC.
The following cases are covered:
- CC == gcc: special case in which we fall back to the default
triplet defined by CROSS_COMPILE;
- CC == XXX != gcc != "": force the use of the specified XXX compiler;
- CC defined both in env and in BUILD_CONFIG: env has higher priority
than BUILD_CONFIG.
This patch solves this unexpected behavior of having the CC value
specified in the environment overwritten by the one defined in
BUILD_CONFIG, preserving the behavior of the other cases.
Test: manual build
