In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

```
with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
Workaround build failure on -fno-common toolchains like upstream
gcc-10. Otherwise build fails as:
ld: ../ipsw-patch/libxpwn.a(libxpwn.c.o):(.bss+0x4): multiple definition of
`endianness'; CMakeFiles/xpwn-bin.dir/src/xpwn.cpp.o:(.bss+0x0): first defined here
Flags that we now set globally:
- CMAKE_OSX_SYSROOT
- CMAKE_OSX_DEPLOYMENT_TARGET
can now be removed.
(cherry picked from commit 8742d5de30dfe2447c0fb56a2e7410b402effc80)
Otherwise the build fails to detect libusb and doesn't build
the 'xpwn' and 'dfu-util' tools.
New tools run but I don't have any suitable devices to test :).
(I believe latest iGadgets need a newer version of xpwn anyway)
This really hase some nice utilities for coping with HFS+ and DMG
format. We're going to use it for extracting the xcode DMG, but it could
be used for more, even generating DMGs.
The reason I'm using the fork instead of the repository from
@planetbeing is thet the fork contains a few fixes, especially for
dealing with symlinks in HFS+ images.
