Call x86-64 __mcount_internal/__sigjmp_save directly
Since __mcount_internal and __sigjmp_save are internal to x86-64 libc.so:
3532: 0000000000104530 289 FUNC LOCAL DEFAULT 13 __mcount_internal
3391: 0000000000034170 38 FUNC LOCAL DEFAULT 13 __sigjmp_save
they can be called directly without PLT.
* sysdeps/x86_64/_mcount.S (C_LABEL(_mcount)): Call
__mcount_internal directly.
(C_LABEL(__fentry__)): Likewise.
* sysdeps/x86_64/setjmp.S __sigsetjmp): Call __sigjmp_save
directly.
