ghc head cross-compilation broken (configure)

It looks like this patch: 6be2c5a7 -- broke configure.ac logic and now the code:

6be2c5a7e91 configure.ac (Ben Gamari                  2022-01-14 19:56:05 -0500  368) # Extract and configure the Windows toolchain

6be2c5a7e91 configure.ac (Ben Gamari                  2022-01-14 19:56:05 -0500  370)     FP_SETUP_WINDOWS_TOOLCHAIN

is run even on non-Windows platform. That means that cross-compiling is broken due to assignment of platform C compiler into the CC variable which is bad thing to do.

I think the most simple fix may be to use inner if blocks instead of test -a here if I'm not mistaken.
