Hi,

the previously applied workaround for sh4 to fix the internal compiler [1]
error with gcc-14 can be dropped now since the gcc-15 package in unstable
is using the new LRA-enabled backend on sh4 which isn't affected by the
previous register allocation problems thanks to the new register allocator
LRA.

Thus, we can drop the workaround to build python3.14 with -Os on sh4:
