b11d65c850 pkg-config-wrapper: mangle PKG_CONFIG_PATH{,_FOR_BUILD} correctly
Previously, mangleVarList would be used which would concatenate the
variables using a space as a separator. Paths are however separated by
`:` in PKG_CONFIG_PATH leading to entries being broken.

This is fixed by introducing mangleVarListGeneric which allows us to
specify the desired separator.

Reproducer for the issue prior to this change:

    $ nix-shell -A pkgsLLVM.wayland
    [nix-shell] $ pkg-config --libs expat
    Package expat was not found in the pkg-config search path.
    Perhaps you should add the directory containing `expat.pc'
    to the PKG_CONFIG_PATH environment variable
    No package 'expat' found
    $ printf 'Host: %s\nBuild: %s' $PKG_CONFIG_PATH $PKG_CONFIG_PATH_FOR_BUILD
    Host: /nix/store/5h308a4ab8w7prcp8iflh5pnl78mayi2-expat-2.2.10-x86_64-unknown-linux-gnu-dev/lib/pkgconfig:/nix/store/z3y9ska2h4l1map25m195iq577g7g3gz-libxml2-x86_64-unknown-linux-gnu-2.9.12-dev/lib/pkgconfig:/nix/store/lbz5m1s0r7zn0cxvl21czfspli6ribzb-zlib-1.2.11-x86_64-unknown-linux-gnu-dev/lib/pkgconfig:/nix/store/rfhvp8r8n3ygpzh8j0l34lk8hwwi3z0h-libffi-3.3-x86_64-unknown-linux-gnu-dev/lib/pkgconfig
    Build: /nix/store/dw11ywy7qwfz53qisz0dggbgix88jah2-wayland-1.19.0-bin/lib/pkgconfig

strace reveals the issue:

    stat("/nix/store/dw11ywy7qwfz53qisz0dggbgix88jah2-wayland-1.19.0-bin/lib/pkgconfig /nix/store/5h308a4ab8w7prcp8iflh5pnl78mayi2-expat-2.2.10-x86_64-unknown-linux-gnu-dev/lib/pkgconfig/expat-uninstalled.pc", 0x7fff49829fa0) = -1 ENOENT (No such file or directory)

In the pkg-config wrapper $PKG_CONFIG_PATH_FOR_BUILD and
$PKG_CONFIG_PATH are concatenated with a space which leads to two paths
being messed up. This issue likely only affects native cross
compilation.

2a9b3b4943 cc-wrapper, bintools-wrapper: support MACOSX_DEPLOYMENT_TARGET with roles
In a typical build environment the toolchain will use the value of the
MACOSX_DEPLOYMENT_TARGET environment variable to determine the version
of macOS to support. When cross compiling there are two distinct
toolchains, but they will look at this single environment variable. To
avoid contamination, we always set the equivalent command line flag
which effectively disables the toolchain's internal handling.

Prior to this change, the MACOSX_DEPLOYMENT_TARGET variable was
ignored, and the toolchains always used the Nix platform
definition (`darwinMinVersion`) unless overridden with command line
arguments.

This change restores support for MACOSX_DEPLOYMENT_TARGET, and adds
nix-specific MACOSX_DEPLOYMENT_TARGET_FOR_BUILD and
MACOSX_DEPLOYMENT_TARGET_FOR_TARGET for cross compilation.

Temporary fix. We definitely do not want to have two separate
implementations.

1ac5398589 *-wrapper; Switch from infixSalt to suffixSalt
I hate the thing too even though I made it, and rather just get rid of
it. But we can't do that yet. In the meantime, this brings us more
inline with autoconf and will make it slightly easier for me to write a
pkg-config wrapper, which we need.

5fad67d361 utils.bash: allow response files in bootstrapping
llvm uses response files in bootstrapping. It’s okay for them to
happen even though we don’t use expandResponseParams here right now.
