Fix hang on undefined symbol in rmb under pragma undefextern
Problem in the pass4.c implementation led to an infinite loop if any
instructions failed to resolve. Instead, if a pass through the loop fails to
resolve anything, bail out since it's clearly pointless to continue trying.

lwcc is based on the PCC compiler code. However, the code has been substantially modified to elminate autoconf, automake, and support for targets not supported by lwtools. In addition, many parts have been substantially rewritten to match the lwtools code style or generally improve readability. Some source files are substantially similar to the same files from PCC and retain the original PCC license. Others, containing original or rewritten code are licensed under the same license as the rest of lwtools.
