Getting a notice/warning/crash at configure time is much easier for a
user than during build time.

This was the first report of its kind in 15 years.

I would change AC_LIB_HAVE_LINKFLAGS if the issue was being reported
10 times in 5 years.

Good point!

Until then, I'll implement a test in Gnuastro after calling `AC_LIB_HAVE_LINKFLAGS'.

Unfortunately this software (CFITSIO) doesn't install shared libraries by default and its static libraries have this problem, so in the next release that implements `AC_LIB_HAVE_LINKFLAGS', many Gnuastro users may fall into this trap.

Thanks again,
