[Samuel Martin <s.martin49@gmail.com>]

Update Config.in and .mk according to the new features.

Remove the pacth the uclibc without long double support, which seems
not necessary anymore.

-[PATCH] Fix compile issue in flann module on uClibc without long double support
-
-uClibc configured without UCLIBC_HAS_LONG_DOUBLE_MATH (because of user
-choice or simply that the arch doesn't provide long doubles) doesn't
-provide fabsl(), breaking the build in the flann module.
-
-Work around it by not providing the long double template specialization.
