uClibc variants do not provide the C99 long double math functions like ceill, powl, etc.. For future compatibility use check_symbol_exists() to check whether these functions are available, and keep the result in HAVE_MATH_C99_LONG_DOUBLE. Use that instead of the fragile Cygwin version check in triodef.h. Fixes build failures under uClibc(-ng) like: ../../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' collect2: error: ld returned 1 exit status Signed-off-by: Baruch Siach <baruch@tkos.co.il>
