gawk-3.0.95 fix for building with Solaris 7 awk

[Paul Eggert]

A gawk 3.0.95 build failed on one of my Solaris 7 hosts because
stamp-eg uses awk, and Solaris 7 awk does not understand the
constructs being used.  Granted, this happened only because I edited
gawk.texi, but still it's a bit of an annoyance and is easily fixed.
Here is a patch.

        * awklib/Makefile.am (stamp-eg): Use $(AWK), not awk, as the
        native awk might not work.
