`which` utility is not shipped by default for example on recent Arch
Linux and then any steps relying on its presence fails, like for example
following Python3 prereq build check:
$ python3 --version
Python 3.9.1
$ make
/bin/sh: line 1: which: command not found
/bin/sh: line 1: which: command not found
/bin/sh: line 1: which: command not found
...
Checking 'python3'... failed.
...
Fix this by switching to Bash builtin `command` which should provide
same functionality.

Commit f98878e4c1 ("cmake.mk: set C/CXX compiler for host builds as
well") has introduced regression as it didn't taken usage of ccache into
the account so fix it by handling ccache use cases as well.
In order to get this working we need to export HOSTCXX_NOCACHE in
rules.mk as well.

Without this, cmake will use whatever CC/CXX is set to, which could be
clang. In that case, at least libjson-c/host will fail to compile.

CMake provides a user package registry (stored in ~/.cmake/packages) and
a system package registry (not available on non-Windows platforms).
The "export(PACKAGE)" command may store information in the user package
registry, and the "find_package()" command may search both user and
system package registries for information.
This sets various variables to disable the use of these package
registries (both saving and retrieval of package information).
This also sets deprecated variables that perform similar functions, in
case external toolchains include older versions of CMake.
