The emake stub recognises that it is being run by lto-wrapper but cannot exec gmake to handle it.


GNU LD has a Link Time Optimization feature which it can speed up by writing a makefile and running whatever tool is pointed to by the $MAKE environment variable. Unfortunately it works in /tmp and emake cannot support this. emake recognises that is is being called by a process named 'lto-wrapper' and instead exec’s "make" to handle the work.


It is possible that "make" is not in the PATH or that it may not be executable for some other reason.


Update the PATH to ensure that GNU make ("make") can be located in it. Check that it runs successfully.
