From: Michel Thebeau <michel.thebeau@windriver.com>

do_sizecheck has a few issues especially with vmlinux image type.

It breaks because KERNEL_OUTPUT is a path relative to ${B}.  When
do_sizecheck runs it does not find the file (because the working
directory is elsewhere) and does not fail.

Also, the image file referenced by KERNEL_OUTPUT may be a link.

Finally, when do_sizecheck deletes the oversized kernel image it leaves
the previously run do_compile task with inaccurate status.

So, do the following:
 - specify that the working directory should be ${B}
 - use ls -L to reference to the real file, and ensure that the link
   file is created
 - keep the oversized image file so the status of do_compile is valid

[YOCTO #3514]
