To make the lzma-loader build with binutils 2.25.1 it is needed to
remove the .MIPS.abiflags section otherwise I get the following compile
error:

mips-openwrt-linux-musl-objcopy -O binary -R .reginfo -R .note -R .comment -R .mdebug -S loader loader.bin
mips-openwrt-linux-musl-objcopy: Warning: Writing section `.text' to huge (ie negative) file offset 0xffffffff80a00000.
mips-openwrt-linux-musl-objcopy:loader.bin[.text]: File truncated

This should close #20487.
