Definitely, yes. This is how we routinely build our software test 
platform for all supported archs, including x86. You can find our 
buildroot-based generator there:

git://git.xenomai.org/mkrootfs.git

Did you provide a gdb backtrace of this problem?

Please check that your CPU as selected in your kernel configuration 
supports sysenter/sysexit if --enable-x86-sep is enabled in your build 
configuration for the user-space programs and libraries.
