hppa: Define __NO_LONG_DOUBLE_MATH so headers are consistent with libm build [BZ #19270]
The attached patch fixes BZ #19270 and the Debian gmt package now builds
successfully.  Aside from the comment, the define of __NO_LONG_DOUBLE_MATH
is similar to that in the generic version of glibc.

Build tested on hppa-unknown-linux-gnu with no observed regressions.
