Compiling and building everything with absolute paths in build!=src, I
get absolute paths in both.

All I care about it to match correctly with '+' in the directory
names. So maybe all I need is to use string_to_regexp and leave the
full path in there.

Ah right, ${srcfilepath} is set up by the testsuite machinery, not
gdb, so it is not guaranteed to match fullname.  I thought you meant
that fullname could not be absolute, and that got me puzzled.  Bottom
line, the testsuite doesn't know what the absolute path is.  We could
pull the dirty trick of asking gdb for it, with an 'info source' and
use that output to match.
