powerpc: Make setjmp/longjmp signature standard
commit c17eb4dca5a353a9dbbb8ad6934fe57af7165e91 upstream.
Declaring setjmp()/longjmp() as taking longs makes the signature
non-standard, and makes clang complain. In the past, this has been
worked around by adding -ffreestanding to the compile flags.
The implementation looks like it only ever propagates the value
(in longjmp) or sets it to 1 (in setjmp), and we only call longjmp
with integer parameters.
This allows removing -ffreestanding from the compilation flags.
Fixes: c9029ef9c957 ("powerpc: Avoid clang warnings around setjmp and longjmp")
