[Buildroot] [PATCH] External toolchain C++ cross-compiler fix

[Thomas Petazzoni]

External toolchain C++ cross-compiler fix

package/Makefile.in resets CXX to "" in TARGET_CONFIGURE_OPTS if
BR2_GCC_CROSS_CXX is not set to 'y'. However, when using an external
toolchain, BR2_GCC_CROSS_CXX is not set even if the toolchain has a
C++ cross-compiler.

This patch adds a new BR2_GCC_CROSS_CXX option in the external
toolchain configuration menu, so that just like BR2_INET_RPC,
BR2_INET_IPV6 and the others, it can be set according to the external
toolchain configuration.

Yah! Someone else had the same problem.

I posted a message about this back on 8/13/2008 with a similar fix (but
not a patch) and never got a reply. I was starting to think it was just
me.

For what it's worth:

No, that's not just you. Not everybody is using Buildroot with the
external toolchain set-up (considering the number of issues faced by
people using it in this setup), and many patches remained unanswered
unfortunately.

Thanks!

Yeah - It's an issue of limited man power, nothing else.
