Especially when using #include directives in imxcfg files, error
messages can be hard to follow because line numbers differ between
preprocessor and source files. Teach the imx image generation tool about
the postprocessed line number / file name directive, so it can give more
useful error messages. Instead of:
error in line 11: Invalid argument
It now says:
$barebox/arch/arm/boards/$som/flash-header-$board.imxcfg:5: Invalid argument
No change in compiled barebox binaries.
