setjmp.h: Fix C++ build and avoid duplicate throw declaration
Commit 21cbb6fe ("unistd.h: put getppid under XOPEN2K8") introduced a new __THROWNL specification for non-leaf throws. It also made use of these in the setjmp.h header. The functions that use this specification (longjmp and siglongjmp) have their extern __libc__* equivalent definition prototype specified using __typeof__ for the internal function signatures. For C++ this copies the throw() specifier, since this is part of the type for C++. The attribute in C is not. This commit explicitly types out the signature for the two functions to be compatible between the C++ and C worlds. An alternative would be to keep the __typeof__ declaration and use the copy attribute. Then the __THROWNL part could be thrown out since the C attribute would be copied and the C++ exception specifier would be part of the signature from __type__. However, since the copy attribute is not supported for all compilers supported by uclibc-ng this is not viable at this time.
