Support static linking with debugging information

[Florian Weimer]

glibc-static contains a stripped version of libc.a.  Why?

There is an unstripped version in glibc-debuginfo, under /usr/lib/debug, 
but it is not a debuginfo-only file.  It seems suitable as input to the 
static linker.

Wouldn't it be more friendly towards developers of you automatically got 
glibc debugging symbols when linking statically?

Thanks,
Florian
