Then just turn on the ARMv4 specific options (-march=armv4t -mno-thumb
-mthumb-interwork -mtune=arm920t ???) for the files that need it.

But as soon as any of these files liks code from libgcc you have to
decide.

Then you should probably still link against a ARMv4 specific libgcc.

If you were building U-Boot's libgcc code with optimization set for
ARMv7 this would not fix anything.
