Subject: [PATCH] Tweak `setup.py` sysroot detection
When crosscompiling, the Python installer expects the C compiler to
be invoked with a `--sysroot` command line option, which then is used
to find additional subdirectories containing headers and libraries.
Because there is no such option present, this is a workaround to use
the environment variable `SERENITY_INSTALL_ROOT` as a fake `--sysroot`
in the detection code.
