[GDBserver] Use pre-generated tdesc as test
Now, these *-generate.c files are only used in GDBserver for unit test. If $development is false (in release), these *-generate.c files won't be used at all. gdb/gdbserver: 2017-09-05 Yao Qi <yao.qi@linaro.org> * configure.srv: Set srv_i386_linux_regobj empty if $development is false. * linux-i386-ipa.c (initialize_low_tracepoint): Don't call initialize_low_tdesc. * linux-x86-low.c (initialize_low_arch): Wrap initialize_low_tdesc with #if initialize_low_tdesc. * linux-x86-tdesc-selftest.c: New file. * linux-x86-tdesc.c: Move code to linux-x86-tdesc-selftest.c.
