[ptxdist] [PATCH] gdbserver: add GDBSERVER_DISABLE_WERROR option

[Alexander Dahl <post@lespocky.de>]

If you activate -Wcast-align globally (which is useful if you build
for older ARM architectures) gdbserver can not compile, because it
throws almost 50 of those warnings and has -Werror set. Would be
better to fix gdb, but as a quick and dirty workaround we can disable
it like this.
