The problem is that the rule for âallâ calls a sub-make, passing it a
CXX_FOR_TARGET evaluated *before* libstdc++-v3 is configured, so the
solution is to delay the expansion of CXX_FOR_TARGET.
Maybe the problem is this:
# We leave this in just in case, but it is not needed anymore.
RECURSE_FLAGS_TO_PASS = $(BASE_FLAGS_TO_PASS)
We could try removing both of these and see what happens...
That won't be enough. We explicitly pass down TARGET_FLAGS_TO_PASS
(including CXX_FOR_TARGET) when recursing for all-host all-target. And
it's not like it would be right to refrain from overriding a number of
variables, CXX_FOR_TARGET included: we want to use different compilers
and options for different stages, rather than taking whatever overrider
the user might have passed for stage1 or so.
