configure: prefer g-variants

For awk and make, we currently check the standard names as found on
a classic GNU-userland system, and then fallback to looking for the
g-named variants as found on a *BSD system.

But it happens that the usual name might also be available on a *BSD
system, so we should first check the g-variant.

configure.ac: respect 'g' variants of libtool/libtoolize

BSD OS'es (OS X for me) provide GNU tools with prefixed 'g'. To find correct
versions of libtool/libtoolize on those systems search also for
glibtool/glibtoolize.

cc/gcc: fix the PR58595 patch

It applies manually with fuzz 2, but ct-ng does not accept any fuxx at all.

So, re-diff the patch so it applies cleanly.

comptools: do not force build of make-3.81 unless really needed

On systems with make-3.82, we forcibly force the build and the use
of make-3.81

But some newer tools break when building with make-3.81. For example,
eglibc-3.18 breaks.

Introduce a new blind options that tools may select if they require
make-3.81. If the system does not have make-3.81, and this option is
selected, then we force the build of make-3.81. Otherwise, we leave
it to the user to decide on his own.

Note that no component selects this option for now. It will come in
later patches as we find them.

If GNU make 3.81 is not found then build it as a companion tool.
