[arch][arm] add rules for arm-linux-gnueabi

Add rules for finding arm-linux-gnueabi toolchain and set no stack
protection.

When compiled under this toolchain, we get the following linking errors
in the final stage:

undefined reference to `__stack_chk_guard'
undefined reference to `__stack_chk_fail'
undefined reference to `__stack_chk_guard'

Stack protection is default on this toolchain but we don't need it.
