It was that simple? :-) Great!
The fix looks good.

My fix uses AC_PATH_TOOL instead of AC_PATH_PROGS when actually searching for the compilers, which will look for the prefixed version of the tool first. The only drawback is that AC_PATH_TOOL does not accept multiple program names to search for, but we don't use that anyway. For each toolchain type, we only ever expect one name for the compiler. If we need to support multiple names, we can add a loop then.
