This patch enables building gcc-2.95.3 using TCC and Mes C Library.
* Disable building DOC
* Avoid running `fixproto'.
* Force running `fixinc'.
* Replace Makefile trickery of creating an libgcc1.a archive, then
extracting the .o files later to create a new libgcc2.a archive.
Instead, keep temporary .o files.
