Set HOSTCC_NOCCACHE and HOSTCXX_NOCCACHE only if they are not
set. This allows recursive calls to "make" to work as intended in the
presence of ccache. Such recursive calls to "make" can for example
happen if one calls "make legal-info" from within a post-build script,
to integrate some results of the legal-info output into the root
filesystem.
Without guarding these variables, a recursive invocation of make would
re-define
HOSTCC_NOCCACHE := $(HOSTCC)
and
HOSTCXX_NOCCACHE := $(HOSTCXX)
at a point in time when HOSTCC and HOSTCXX already point to ccache.
It used to work by "accident" until
ca6a2907c2 ("make: support: use `command
-v' instead of `which'"), due to how "which" was behaving when invoked
with multiple arguments. After switching to "command -v", which
behaves different with multiple arguments, this HOSTCC_NOCCACHE
redefinition problem surfaced. Even though
ca6a2907c2 has since then been reverted
for other reasons, it does make sense to guard the definition of
HOSTCC_NOCCACHE and HOSTCXX_NOCCACHE to not rely on a side-effect of
using "which".
