How can I configure to build x86_64?
When I build GHC (with msys2), it always builds i386 and I haven't spotted
the option in ./configure to choose a x86_64 release.
This is implicitly determined by the toolchain you use. So, probably
you have the i686 msys2 installed, while you would need the x86_64
version. Given, that your operating system (and thus your hardware)
is also x86_64.
It turns out if I have 64-bit prebuilt ghc installed and exported in PATH,
the build system will detect it and build a 64-bit ghc from source code.
