Fix warnings building linux-atomic.c and fptr.c on hppa64-linux
The file fptr.c is specific to 32-bit hppa-linux and should not be included in LIB2ADD on hppa64-linux. There is a builtin type mismatch in linux-atomic.c using the type long long unsigned int for 64-bit atomic operations on hppa64-linux. 2021-10-27 John David Anglin <danglin@gcc.gnu.org> libgcc/ChangeLog: * config.host (hppa*64*-*-linux*): Don't add pa/t-linux to tmake_file. * config/pa/linux-atomic.c: Define u8, u16 and u64 types. Use them in FETCH_AND_OP_2, OP_AND_FETCH_2, COMPARE_AND_SWAP_2, SYNC_LOCK_TEST_AND_SET_2 and SYNC_LOCK_RELEASE_1 macros. * config/pa/t-linux64 (LIB1ASMSRC): New define. (LIB1ASMFUNCS): Revise. (HOST_LIBGCC2_CFLAGS): Add "-DLINUX=1".
