Thanks for taking it up. In fact, you don't need parallel build on
a SMP machine to see the bug. Since there are no dependencies on
s-libi77, s-libf77, s-libu77 and s-libe77, with "make -j 100000" in
libf2c, GNU make will start to build s-libi77, s-libf77, s-libu77 and
s-libe77 at the same time along with other targets. Since there are
no rules for them, the build will fail.
