[Bug runtime/11229] New: Error message for CONFIG_UTRACE could mention kernel development headers


The error message encountered when kernel_config[CONFIG_UTRACE] != "y" could
mention the possibility that kernel development headers are not installed.

I have attached a suggested quick-fix. If the CONFIG_UTRACE is blank, the
semantic error will prompt the user to check that devel headers are installed.

e.g.: 
semantic error: process probes unavailable without kernel CONFIG_UTRACE, ensure
kernel devel headers are installed and CONFIG_UTRACE is enabled while resolving
probe point
process("/home/chwang/runtime-EclipseApplication/CallGraphDemo/Debug/eag").function("*").call
