Okay found a unique bug with grsecurity and glibc's install scripts. I 
honestly
don't know how to fix it (or if we even should) but I'll tell you everything
that happens.

=== PRECONDITIONS ===
1) grsecurity kernel with CONFIG_GRKERNSEC_LINK enabled y

=== STEPS TO REPRODUCE ===
1) just cast -c glibc

=== POST-CONDITIONS ===
1) glibc fails to install due to test-installation.pl failing

=== REASONS ===
After further experimentation I hacked at the test-installation.pl to make it
work around grsecurity preventing linking in the /tmp directory. The script
creates a small test C file in /tmp it then compiles the binary into /tmp then
tries to ldd the file and parse the output. Since grsecurity prevents linking 
it
doesn't output anything and the test-installation.pl script thinks the compile
failed to link somehow.  I got around this by hacking at the script making it
use /root to run the binary from instead of /tmp.

I honestly don't know if we should worry about this.  I just figured I'd 
report
this somewhere so someone else can make a decision.
