kexec-tools: Set -fno-PIC on aarch64
PATCH 1/1 kexec-tools: Set -fno-PIC on aarch64
From: Mingli Yu <[email protected]>
As seen in GCC's gcc/config/aarch64/aarch64.c, -fPIC with large code model is unsupported. This fixes the "sorry, unimplemented" errors when building with compilers defaulting to -fPIC.
