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.

<`Kumba> ths: given the SHN_UNDEF thing is a hack, what's the preferred solution?

<ths> For fakeroot the simplest trigger is "fakeroot file /bin/ls".

<ths> `Kumba: I haven't found a better one yet.

<ths> Probably marker symbols around the stub section, and then exclude it from the link map.

     7
<ths> This needs a ld change.
