[Qemu-devel] [PULL 02/18] linux-user: Remove the unused "not implemented" signal handling stubs

[Laurent Vivier <laurent@vivier.eu>]

From: Peter Maydell <peter.maydell@linaro.org>

Now we've dropped unicore32, all of the architectures we support
for linux-user implement the signal handling routines. The
dummy "just print a message" versions are unimplemented, so we
can drop them entirely.
