Lluís Batlle i Rossell 585ba8c27f Big fixes in the cross build:
- 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.

/* Fix for NIXPKGS-79: when doing host name lookups, when
nsswitch.conf contains a line like
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
don't return an error when mdns4_minimal can't be found. This
is a bug in Glibc: when a service can't be found, NSS should
continue to the next service unless "UNAVAIL=return" is set.
("NOTFOUND=return" refers to the service returning a NOTFOUND
error, not the service itself not being found.) The reason is
that the "status" variable (while initialised to UNAVAIL) is
outside of the loop that iterates over the services, the
"files" service sets status to NOTFOUND. So when the call to
find "mdns4_minimal" fails, "status" will still be NOTFOUND,
and it will return instead of continuing to "dns". Thus, the
line
hosts: mdns4_minimal [NOTFOUND=return] dns mdns4
does work because "status" will contain UNAVAIL after the
failure to find mdns4_minimal. */
