On solaris 11.4, the system libc has a definition of sqrt leading configure
to believe that linking libm is unnecessary. Applying a patch locally to
change
AC_SEARCH_LIBS([sqrt], [m]) to
AC_SEARCH_LIBS([atan], [m])
fixes the problem.

atan was picked at random from the symbols that couldn't be found in
building temacs.
