ARM: 9138/1: fix link warning with XIP + frame-pointer
When frame pointers are used instead of the ARM unwinder,
and the kernel is built using clang with an external assembler
and CONFIG_XIP_KERNEL, every file produces two warnings
like:
arm-linux-gnueabi-ld: warning: orphan section `.ARM.extab' from `net/mac802154/util.o' being placed in section `.ARM.extab'
arm-linux-gnueabi-ld: warning: orphan section `.ARM.exidx' from `net/mac802154/util.o' being placed in section `.ARM.exidx'
The same fix was already merged for the normal (non-XIP)
linker script, with a longer description.
Fixes: c39866f268f8 ("arm/build: Always handle .ARM.exidx and .ARM.extab sections")
