I don't see any -no-pie lines.

I think the issue is that the -no-pie configure test looks for 'clang' or 'gcc'.

But ${CC} for me at that point is 'x86_64-pc-linux-gnu-gcc'. If I set CC=gcc,
it appends -no-pie and the test passes (all of them do, in fact).

I think it'd be better to use AX_CHECK_COMPILE_FLAG or similar?

Alternatively, *clang* or *gcc* may work (but a bit fragile).

Uploaded the full build log at https://dev.gentoo.org/~sam/tmp/gawk-5.1.65.log
and my config.guess is gnuconfig from 2022-05-08. For convenience,
I've uploaded that at 
https://dev.gentoo.org/~sam/tmp/gawk-5.1.65-config.guess-2022-08-23.

This seems to be the only failure (tried with --keep-going passed to make).
