Subject: ARM: 9226/1: disable FDPIC ABI
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3d47ff25685e76c24565779681f652b7ff2b10f0;p=linux.git

ARM: 9226/1: disable FDPIC ABI

When building with an arm-*-uclinuxfdpiceabi toolchain, the FDPIC ABI is
enabled by default but should not be used to build the kernel.
Therefore, pass -mno-fdpic if supported by the compiler.
