I do not understand what you mean, for cross-compiling, you should pass
a --host option to configure. If you do not pass a --host option, the
build machine compiler is used.

Probably, but you do not give us enough information, what architecture
is your build machine ? What version of the compiler, etc...

No, it is useless, the compilation of Xenomai user-space support is
really fast, so, you simply have to not copy on your target the
libraries that you do not use.
