package/gcc: remove arm soft patch
The patch refers to [1] which says "Unfortuantely, arm-gcc defaults to
generating code for armv5t." Since we always explicitly pass the target
CPU for ARM, the default CPU shouldn't matter.
As suggested by Arnout [2], a test based on qemu_arm_versatile_defconfig
has been done without this patch and there is no regression.
