[lto][patch] fix "make -j K check"

In a "make -j K check", the environment variables that make sets were
confusing the make invocations done by ltrans.  This was resulting in
errors like

make[4]: *** read jobs pipe: No such file or directory.  Stop.
make[4]: *** Waiting for unfinished jobs..

showing up in the test logs. This patch fixes it by clearing the make
variables in ltrans-driver.
