#     powerpc: Discard .branch_lt section
#     
#     When building a 32 bit powerpc kernel with Binutils 2.31.1 this warning
#     is emitted:
#     
#      powerpc-linux-gnu-ld: warning: orphan section `.branch_lt' from
#      `arch/powerpc/kernel/head_44x.o' being placed in section `.branch_lt'
#     
#     As of binutils commit 2d7ad24e8726 ("Support PLT16 relocs against local
#     symbols")[1], 32 bit targets can produce .branch_lt sections in their
#     output.
#     
#     These sections should be empty for the kernel build so discard them for
#     both PPC64 and PPC32.
