You're absolutely right. It turns out that while we have test case for 
prebuilt libraries, it does not catch this bug. I'll reproduced it already 
and will fix tomorrow.

It's controlled by line 150:

flags builtin.response-file LIBRARY_OPTION <toolset>borland : -l : unchecked ;

is something different needed? For example, if no option at all is needed, 
just library name, one should be able to replace "-l" with "".
