Comment:

 You're also building for x86_64 on an ARM system. Cross-compiling is
 tricky at the best of times.

 There seems to be a cascade of errors in the configure script, each
 causing later checks to fail, starting with this:
 {{{
 configure:24350: checking for pid_t
 configure:24350: /usr/bin/clang -c -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk -arch
 x86_64 -I/opt/local/include

 Including both arm and i386 versions of the headers isn't going to work
 very well, naturally.
