[PATCH][committed] fortran, openmp: Add default case to trans-openmp switch in order to avoid -Wmaybe-uninitialized warning

[Tamar Christina]

Similar to g:67356e61bd58ed17e4d5e67624a17a39e592fb5d
this adds a default case such that we don't get a warning on
type being used uninitialized.

This fixes the armhf bootstrap.

Bootstrapped Regtested on aarch64-none-linux-gnu,
arm-none-linux-gnueabihf, x86_64-pc-linux-gnu
-m32, -m64 and no issues.

Pushed to master as obvious.

Thanks,
Tamar
