Maybe we should have configure assume CC=clang for arm64.

--- Comment #4 from Anastasius Focht focht@gmx.net --- Hello folks,
adding some information here...
The clang requirement comes from bug 38886 ("AArch64 platforms: ABI Problems wrt varargs (needs arm64 specific __builtin_ms_va_list)").
https://source.winehq.org/git/wine.git/commitdiff/8fb8cc03c3edb599dd98f369e1... ("arm64: Use __builtin_ms_va_list and __attribute__((ms_abi)) on arm64.")
GCC project tracking bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87334

clang is a hard requirement for aarch64 target unless gcc implements '__builtin_ms_va_list' in about 10 years (given the interest so far).
Options:
(1) Assume people building Wine on/for aarch64 are knowledgeable enough to pass proper compiler environment to 'configure'. This obviously didn't work here otherwise there would be no bug report.
(2) Improve the error message by providing a hint how pass clang as compiler.
(3) Have 'configure' override CC with clang on aarch64 by default.
$ wine --version wine-6.0

--- Comment #5 from Jacek Caban jacek@codeweavers.com --- Once we move all code that needs __builtin_ms_va_list to PE files (where we can just use default va_list), we will not need ms_abi attribute. I think that's the long term solution.

--- Comment #6 from Fabian Maurer dark.shadow4@web.de --- What's the state on this? Seems to compile fine with gcc and llvm-mingw as soon as I had the latter installed. No change for CC needed.

That's because you have llvm-mingw in your path, retry with just gcc and no clang/mingw.
