Fix the error message for romstage when .bss or .data are non-zero

The error message from romstage is annoying and misleading:
    "Do not use global variables in romstage"

Because it can occur even when global variables are not used
    in some circumstances, but also because it gives you only a rough
    idea where to look. This change sucks but sucks less. We still don't
    know which file the problem is in but at least we know if it is data
    or bss.

Replace the error message with something that provides more information
    and less guessing on the part of the script:
    ".bss is non-zero size in romstage which is not allowed -- global variable?"
    or
    ".data is non-zero size in romstage which is not allowed -- global variable?"

To test: build coreboot as normal. It builds.
    Add
    char d[32];
    to romstage.c and get the first error message; add
    int x = 32;
    to romstage.c and get the second.
