Add CMake long double cross-compile defaults (#3683)
HDF5 performs a couple of checks at build time to see if long double
values can be converted correctly (IBM's Power architecture uses a
special format for long doubles). These checks were performed using
TRY_RUN, which is a problem when cross-compiling.
These checks now use default values appropriate for most non-Power
systems when cross-compiling. The cache values can be pre-set if
necessary, which will preempt both the TRY_RUN and the default.
Affected values:
H5_LDOUBLE_TO_LONG_SPECIAL (default no)
H5_LONG_TO_LDOUBLE_SPECIAL (default no)
H5_LDOUBLE_TO_LLONG_ACCURATE (default yes)
H5_LLONG_TO_LDOUBLE_CORRECT (default yes)
H5_DISABLE_SOME_LDOUBLE_CONV (default no)
Fixes GitHub #3585
