libgloss: regenerate aclocal.m4 & configure w/newer versions
Regenerate the files using automake-1.15 & autoconf-2.69 to match the
binutils/gdb/gcc projects. Ran:
libgloss $ find -name configure.ac -printf '%h\n' | while read d; do
(cd $d; export WANT_AUTOCONF=2.69 WANT_AUTOMAKE=1.15;
aclocal-1.15 -I.. && autoconf-2.69); done
