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.

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.
