- Before this changes, cflags and ldflags for the native and the cross compiler got mixed. Not all the gcc-wrapper/gcc-cross-wrapper variables are independant now, but enough, I think. - Fixed the generic stdenv expression, which did a big mess on buildInputs and buildNativeInputs. Now it distinguishes when there is a stdenvCross or not. Maybe we should have a single stdenv and forget about the stdenvCross adapter - this could end in a stdenv a bit complex, but simpler than the generic stdenv + adapter. - Added basic support in pkgconfig for cross-builds: a single PKG_CONFIG_PATH now works for both the cross and the native compilers, but I think this should work well for most cases I can think of. - I tried to fix the guile expression to cross-biuld; guile is built, but not its manual, so the derivation still fails. Guile requires patching to cross-build, as far as I understnad. - Made the glibcCross build to be done through the usage of a gcc-cross-wrapper over the gcc-cross-stage-static, instead of using it directly. - Trying to make physfs (a neverball dependency) cross build. - Updated the gcc expression to support building a cross compiler without getting derivation variables mixed with those of the stdenvCross. svn path=/nixpkgs/branches/stdenv-updates/; revision=18534
