+GNU ld's RISCV port does not support IFUNC. ld -no-pie produces no

+Subject: [PATCH] Fix build with GCC 10 when long double = double.
+
+On platforms where long double has the same ABI as double, glibc
+defines long double functions as aliases for the corresponding double
+functions. The declarations of those functions in <math.h> are
+disabled to avoid problems with aliases having incompatible types, but
+GCC 10 now gives errors for incompatible types when the long double
+function is known to GCC as a built-in function, not just when there
+is an incompatible header declaration.
+
+This patch fixes those errors by using appropriate
+-fno-builtin-<function> options to compile the double functions. The
+list of CFLAGS-* settings is an appropriately adapted version of that
+in sysdeps/ieee754/ldbl-opt/Makefile used there for building nldbl-*.c
+files; in particular, the options are used even if GCC does not
+currently have a built-in function of a given function, so that adding
+such a built-in function in future will not break the glibc build.
+Thus, various of the CFLAGS-* settings are only for future-proofing
+and may not currently be needed (and it's possible some could be
+irrelevant for other reasons).
+
+Tested with build-many-glibcs.py for arm-linux-gnueabi (compilers and
+glibcs builds), where it fixes the build that previously failed.
+
