Subject: Fix linker errors when building EGLIBC.

We built the cross-compiling GCC without a Stack Smashing Protector
(SSP) by passing the option '--disable-libssp' to its configure script
because otherwise we'd get a configure error when building GCC (as
mentioned in section 5.5.1 of Linux From Scratch version 7.0 and
experienced first-hand by this author).  However, EGLIBC's configure
script incorrectly detects support for SSP and prepares EGLIBC to be
linked with SSP symbols.  As a result, NSCD (EGLIBC's Name Service Cache
Daemon) fails to link due to undefined references to symbol
'__stack_chk_guard'.

So, we need to pass 'libc_cv_ssp=no' to EGLIBC's configure script to
tell it explicitly that we don't have SSP support in our build of GCC.
