libc/glibc: both glibc and eglibc have pkgversion and bugurl

Well, all eglibc version we support do, and latest glibc versions
we support do.

Not all glibc versions do, but older versions simply ignore the
unrecognised ./configure flags.

     1 Original patch from H.J. Lu, as reported there:

     2 http://www.nabble.com/PATCH:-Use-short-for-fnstsw-td14775171.html

     3 

     4 fnstsw stores 16bit into %ax. The upper 16bit of %eax is unchanged.

     5 The new assembler (binutils-2.18.50.0.4 and up) will disallow "fnstsw %eax".
