Hi,
I noticed that a cross-compiler produces an unusable libstdc++.so
that contains an unresolved reference to aligned_alloc instead of
posix_memalign, or whatever is actually available.
Therefore it is impossible to link any C++ programs against the
libstdc++.so that comes with the cross-compiler.
That happens for instance in the following configuration:
--target=arm-linux-gnueabihf.
The attached patch adds a link test for the memalign function
and fixes the cross-build for me.
Is it OK for trunk?
OK.
Presumably we should have this for other cross targets too.
