Bootstrapping core-updates fails with mpc-1.2.1dev |

Hello,
after the release of mpc-1.2.0, I tried to update the version in core-updates.
More precisely, I used a tarball of the current master under the name of
mpc-1.2.1dev, with an additional commit. Then bootstrapping fails.
For someone with bayfront access, the build log is in
/var/log/guix/drvs/ay/qa5whpm2nq3667ff69xzqvn9119b8g-gcc-cross-boot0-7.5.0.drv.gz
It ends with this:
...

Does this ring a bell? I do not quite see how this can be related to the mpc
version used for bootstrapping; and the phase unpack-gmp&co is carried out
and does unpack my mpc-1.2.1dev.tar.gz after gmp and mpfr.
What is strange in the compiler line above is that gmp and mpfr are
referenced by -I directives, but mpc is not.
Is there anything special with gmp-7.5.0 that prevents it from being compiled
with a newer mpc? The build log also shows that gmp and mpfr are compiled in
their respective subdirectories, but mpc is not.
