Changes since v1:
- Completely rewrite of the patch to set ENABLE_FLOAT128 at libstdc++
build time and undef _GLIBCXX_USE_FLOAT128 when building user code.

In order to use __float128 in C++ it's necessary to check if the
compiler enabled its support too when building user code.
This patch changes the behavior at libstdc++ build by setting
ENABLE_FLOAT128, which is used to set the value of the exported macro
_GLIBCXX_USE_FLOAT128.
Now that we're in stage 1 we can make this change. The patch looks
right so I'll go ahead and commit it to trunk (it shouldn't interfere
with testing any last-minute fixes needed for gcc-8).
Thanks for fixing this, Tulio.
