When looking for C compilers, xcompile uses the "" prefix to "gcc" and
"clang" as a last-resort option. This fails in environments where such
default names are blocked to prevent "unclean" builds - such as Chrome
OS.
Allow overriding this prefix using the GENERIC_COMPILER_PREFIX variable
that is hopefully both descriptive enough to suggest what it is for and
unusual enough to not trigger by chance.
