Comment (by skrah):

 It might be worth pointing out that mpdecimal uses the environment
 MACHINE=universal on macOS and AIX for generating a single universal
 header file. In the case of macOS, this is for arm64/x86_64/ppc/ppc64.

 So, on arm64 I can do:

 $ ./configure CFLAGS="-arch arm64 -arch x86_64" CXXFLAGS="-arch arm64
 -arch x86_64" LDFLAGS="-arch arm64 -arch x86_64" LDXXFLAGS="-arch arm64
 -arch x86_64" MACHINE=universal

 make && make check passes. Library info gives:

 $ lipo -info libmpdec/libmpdec.4.dylib

 Architectures in the fat file: libmpdec/libmpdec.4.dylib are: x86_64 arm64
