<endian.h> may not exist on other systems, don't include it
directly, but include "compiler.h", which either includes
it or provides a suitable alternative if possible.

This reverts commit 5c0e165.

The fix_size scripts is not necessary for newer ARM toolchains,
it is however necessary for the older ARM toolchains (gcc-5 and older).

The original reason to drop fix_size was that it doesn't work on MIPS.
With this patch we add the -i flag so that we ignore unknown images
and can succesfully build MIPS images.

Defining only _BSD_SOURCE is deprecated with version 2.20 of
glibc. It has been replaced by _DEFAULT_SOURCE. The manpage says
that code which wants to work in the same way on both old and new
versions of glibc should simply define both symbols.

Also move the definition up in fix_size as those feature flags
should be defined before including any standard headers.

Instead of passing the offset to the fix_size tool check the image to
fixup for a valid header so that only recognized files are fixed up.
This makes the usage of this tool safer.

this will allow to write the size of barebox at an offset of the binary

this is needed for ARM when using relocated binary
