BaseTools: Use BUILD_CC when checking gcc version in DevicePath

When checking the version in DevicePath's Makefile, use BUILD_CC instead
of assuming "gcc".  BUILD_CC is set in header.makefile and is the
compiler that will actually be used to build DevicePath.  It defaults to
"gcc", but may be overridden.
