[Buildroot] QWidget cannot check for file existence when cross compiling

[Thiago A. Corrêa]

I had seen this in classpath.

It's a problem with it's configure. Only God knows why, but they added
a check in the configure script that when crosscompiling, it will just
fail with Qt integration enabled. There are 2 ways to fix it: drop the
--enable-qt in classpath.mk or patch configure.

Kind Regards,
