Heh, Jan and Simon have reported this already.  The code should work, given our
move to require C99.  Options have been discussed in:

    https://sourceware.org/pipermail/binutils/2021-April/116325.html

Basically, AC_PROG_CC_C99 is deprecated in newer Autoconf, so the discussion
is talking about maybe upgrading to Autoconf 2.71.


That said, given 3 different people have now run into this and any conversion
to Autoconf 2.71 might be a while, please go ahead and commit the trivial
fix to unblock everyone.  Thanks.
