[PATCH v2] Unconditionally declare strsignal

[Christian Biesinger]

Currently, newlib does not declare strsignal if DEFS_H is defined,
ostensibly to work around a gdb bug. However, gdb itself compiles
even with this ifndef removed, and this makes sim (another part of
gdb) fail to compile.

Since it is not clear exactly what issue this was working around,
this patch just replaces that ifdef with the correct check,
i.e. __POSIX_VISIBLE >= 200809.
