[Buildroot] [PATCH] package/uclibc: enable long double math for xtensa

[Max Filippov]

It fixes the following build failure for packages that expect long
double support in libm:

  Linking C executable winpr-hash
  ../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `powl'
  ../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `fmodl'
  ../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `ceill'
  ../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `log10l'
  ../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `floorl'

Fixes:

Mainline status: patch submitted.
