A similar hack for gold to those I've added for BFD ld, ar, nm and
ranlib. The idea being to give users a clue, and cut down on the
number of invalid bugzillas. You'll get something like
hello.a(hello.o): plugin needed to handle lto object
.../crt1.o(.text+0x20): error: undefined reference to 'main'
rather than just
.../crt1.o(.text+0x20): error: undefined reference to 'main'
OK to apply?
