universe: Permit requesting a specific version of GCC
If USE_GCC_TOOLCHAINS is set to a value matching the pattern 'gcc*', use that as the GCC version. For example, USE_GCC_TOOLCHAINS=gcc16 would use amd64-gcc16 for amd64, etc. If the variable is set to a value that doesn't match that pattern, use the default version.
