PR 30437 [4.0/4.1/4.2/4.3 Regression] -Wno-all is rejected

[Manuel López-Ibáñez]

:ADDPATCH fortran:

Wno-all is currently rejected on mainline. This simple patch fixes the
issue. However, a better fix would be to move Wall to common.opt but
let it be handled by each front-end. I was not able to implement this,
front-ends were not able to catch Wall, any suggestions ?

This patch bootstraps and does not generate new regressions. OK for mainline?
