Reopened.

That "bug" would be fixed it the "-fprofile-use" option were not given in
the directories that are expected to be empty of ".gcda" files. We could
get the Makefile's formula to look for ".gcda" files first and compile the
corresponding ".c" files, then compile the remaining ".c" files _without_
using "-fprofile-use" -- not much to figure out and no spurious warnings.


The _other_ bugs are:

2. ... _every_ file in gcc_build/zlib failed to create it's accompanying
  ".gcda" files ... and we miss an opportunity to optimize this library. 

3. There is a "-Werror" to be fixed. Use: "i386.o-warn = -Wno-error"

4. The Makefile won't restart in the correct spot if the build breaks.
  It takes hours to re-configure and re-build what it already has done.

5. The "C" and "Ada" Languages are being profiled (for the most part) but
 the c++,fortran,java,objc,obj-c++ compilers are NOT profiled at all.
