hgcc, etc

This patch replaces hgcc.sh by hardcoding -pie and -fstack-protector-all. I 
have tested it on glibc and gcc and it builds both perfectly. There are a ton 
of failures from binutils testsuite. I'm almost sure the errors are in the 
teststuite itself, not with binutils apps. This patch will build anything 
not-static with -pie. -fstack-protector-all should/is filtered from -DIN_GCC, 
-D_KERNEL_, nostartfiles, etc because it offers no benifit guarding a lib, 
and only manages to contaminate the libs.

On my end this all looks pretty good and I'm ready to freeze this toolchain 
now that it seems to work pretty well. This patch is for x86, I can help PPC 
users to get this working for them too, or any other elf platform.

gcc-3.3.3 is the first gcc, as far as I can tell. that can build without 
textrel, so I definetly want to use it over 3.3.2. Still need a good 
glibc-2.3.3 tarball. ncurses-5.4 has a long list of bugfixes that might be 
good to add too.

While iptables is being worked on I'll try to start organizing the first book 
with the toolchain stuff, and it can be added to after. It wouldn't be too 
difficult to add Pam/cracklib at this stage unless anyone objects, or thinks 
it should stay in blfs. Shadow can take advantage of this.

Is iptables a blfs thing or will it be in the base? I feel iptables should be 
installed with nettools. If iptables is blfs, so should nettools. If they're 
both in the base thats fine with me, but I sorta feel networking should get 
its own chapter, which can deal with iptables, openssl, ipsec, snort, etc.
