[vlc-devel] [PATCH] configure: use CC_FOR_BUILD for the build system compiler

[Steve Lhomme]

This is a variable commonly used with AX_PROG_CC_FOR_BUILD.
If our legacy BUILDCC is set, we use that.
If nothing is set we still look for a c99 compiler.

Internally we still compile with BUILDCC

sans CFLAGS_FOR_BUILD which can't be handled with the current system
