Applying the attached patch to a downloaded source tarball of GNU make
4.2.1 should allow it to work correctly with the latest GNU libc
versions.
Note the info at the top of the patch: if you're building from a
tarball you need to "touch" a few files to ensure that it doesn't try
to rebuild autotools files.
Apply this patch to the results of unpacking a make 4.2.1 tarball,
then run the following commands:
touch aclocal.m4
touch Makefile.in
touch configure
Now you should be able to reconfigure and rebuild.
