I'm including below our patch for compiling a HiPE-enabled system on
glibc-2.3 systems like RedHat 8.0. It looks like a trivial change,
but it required careful study and testing.

RH5 will only work if those that care about it do the port themselves.
The issue is, again, hipe_x86_signal.c and it's dependency on C library
internals. We do support RH6.2/7.0/7.1/7.2/7.3/8.0 and Solaris/x86 8.
