test case to reproduce the the failure

When attempt to build a simple code including one assembly file and one c code
file while calling a c function from the assembly code and using the lto in
linkage stage I encountered an error in the lto-wrapper where ld returned 1
exit status, with file not recognized: file truncated.

the build has been done in windows machine.
