A solution is to use gmp 4.2.1 which is LGPLv2+.

Another is to have gmp allow linking with GPLv2 programs. My impression
on last conversation with the gmp developers is that they do not
consider that a serious problem to dual license gmp GPLv2/LGPLv3. I
think bring the issue up to them and mentioning the projects that it
affects, would help solve the issue.
