[U-Boot] Full paths when compiling

[Simon Glass]

Hi Masahiro,

I notice that when compiling I get the full paths to the source when I
use __FILE__:

/home/sjg/c/src/third_party/u-boot/files/cros/lib/readwrite.c:
vboot_rw_select_kernel: VbSelectAndLoadKernel: 65552
/home/sjg/c/src/third_party/u-boot/files/cros/lib/vboot.c:
vboot_set_error: Stage 'VbSelectAndLoadKernel' produced vboot error
0x10010
/home/sjg/c/src/third_party/u-boot/files/cros/vboot/stages.c:
vboot_run_stage: Error: stage 'rw_selectkernel' returned -1

Is there a way to only get the relative path, say "cros/lib/readwrite.c"?

Regards,
Simon
