If a platform does not define "long-double-fcts = yes" in its Makefiles and it does define __NO_LONG_DOUBLE_MATH in its installed headers, it will currently create exported symbols for __finitel, __isinfl, and __isnanl that can't be reached from userspace by correct use of the finite(), isinf(), or isnan() macros in <math.h>. To avoid this situation, by default for such platforms we now no longer export these symbols, thus causing appropriate link-time errors. However, for platforms that previously exported these symbols, we continue to do so as compat symbols; this is enabled by adding LDBL_CLASSIFY_COMPAT to math_private.h for the platform. For tile, remove the now-unnecessary exports of those functions from libc and libm.
