Yes, you can contribute the same code under LGPLv2.1+ to glibc and LGPLv3+ 
to GMP.  The standard FSF assignment generally allows contributors to use 
their own contributions under such terms as they see fit; it's adding and 
relicensing code from other GNU projects, where you don't have relicensing 
approval from all significant contributors, that needs FSF approval for 
the relicensing.
