The ICONV_OMITS_BOM flag is about the libc iconv that Git will be linked
against. But this is checking the iconv tool. For a system that is using
musl across the board, that would work. But it might not always be the
case (in particular, I don't know if people statically link some
binaries against musl; certainly I've seen people do it with dietlibc).

I think we should be test-compiling a small program, similar to the way
OLD_ICONV works (though I guess we may even need to run the result to
see what happens).

Originally, I wrote a C program for AC_RUN_IFELSE, but I found out the
complicated of OLD_ICONV and NEEDS_LIBICONV, then I switch to this
approach.

But, your reasoning makes sense. I think people could build a static-linked
git binary for a clean-room build system.

I'll pursue the C program in the re-roll.
