@branfosj It doesn't make sense to use this patch for Bison-3.5.3-GCCcore-9.3.0.eb, but patching Bison-3.5.3.eb does make sense?

Fixed in c3ba286

@boegelbot please test @ generoso

I tested (manually) building Bison 3.5.3 in an old SL6 Singularity container, fails without the patch as reported in #12202, works with the patch:

Singularity> bison --version
bison (GNU Bison) 3.5.3

Singularity> cat /etc/redhat-release
Scientific Linux release 6.9 (Carbon)

Singularity> gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18)

@boegel: Request for testing this PR well received on generoso

Test results coming soon (I hope)...
