Summary

0000936: arm920t build fails due to gcc not allowing `bx`

Description

selecting arm920t in buildroot and allowing uClibc to use BX
causes the compiler to fail to build ldso.sO with the error
that BX is not supported by the processor.

The fix is to change ARM920T to -march=armv4t (armv4 with thumb)
as this is the correct mode for any ARM9 cpu with the T suffix.

affixed is a patch to change -march=armv4 to -march=armv4t for
ARM920T and ARM922T.
