newlib: Add more FreeBSD files for non LDBL_EQ_DBL support

For RISC-V, AArch64, i386, and x86_64

- k_tanl.c is required for tanl; the linker will report `__kernel_tanl`
  not found when tanl is called.
- s_cospil.c and s_sinpil.c are added for cospil and sinpil, which are already
  available for ld80 but not for ld128.
