[Buildroot] [PATCH] package/pcm-tools: fix build with GCC 4.8.2

[Carlos Santos]

Pass $(TARGET_CONFIGURE_OPTS) as arguments to make and add "-std=c++11"
to CXXFLAGS, forcing C++ 2011 standard (it's experimental in GCC 4.8.2
but goot enough to build pcm-tools).

TARGET_CONFIGURE_OPTS were already passed as argument: they are already
passed to the right hand-side of $(MAKE), so I dropped this particular
change.

This was enough to fix the build failure.

Applied with this change. Thanks!
