gentoo-overlay/dev-libs/bglibs/files/bglibs-1.104-parallel-fix.patch

Fixes for parallel compile.

- Redirection straight to an output target that is later used for dependancies
  is not safe. The output file must be come into existence atomically.
- libtool-2.x writes to .o AND .lo, regardless of the -o parameter. Because of
  this, if you get a run order of compile then libcompile and makelib
  simultaneously, there is a chance that the .o file from the original compile
  can vanish and cause the makelib to fail. To deal with this, we split the
  libraries target into shared and non-shared, and deliberately call the build
  process as 3 phases: libs-shared, libs-static, all
