For an unknown reason gcc tries to link in crti.o when building with a
glibc toolchain (this does not happen with other targets). Prevent this
by telling gcc explicitly to not do that.
Fixes the following build error:
/home/jonas/git/lede/staging_dir/toolchain-mips_24kc_gcc-5.5.0_glibc/lib/gcc/mips-openwrt-linux-gnu/5.5.0/../../../../mips-openwrt-linux-gnu/lib/crti.o: In function `_init':

Change the Makefile to use LTO for better code optimisations. Gains are
very low, only 270 bytes saved, but it's only Makefile changes.

Some bootloaders set a cache cohenrency to a very slow mode. Use code from
Linux kernel to set it to "Cacheable, noncoherent, write-back, write
allocate".
Perfomance impact is significant on TP-Link EAP245 board, kernel
decompression time fall from 33 seconds to less than 1.

According to the calling convention of the o32 ABI the caller
function must reserve stack space for $a0-$a3 registers in case
the callee needs to save its arguments.
The assembly code of the loader does not reserve stack space for
these registers thus when the 'loader_main' function needs to save
its arguments, those will be stored in the 'workspace' area instead
of the stack.
Because the workspace area is also used by other part of the code, the
saved register values gets overwritten and this often leads to failed
kernel boots.
Fix the code to reserve stack space for the registers to avoid this
error.

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.

The generic kernel cmdline parser ignores argv[0], this caused a
regression for all lzma-loader based boards with linux 4.1

This allows to load the resulting image directly
from RouterBOOT.
