build regression

[Tom Tromey]

On the trunk, libgcj fails to build:

/home/tromey/gnu/Trunk/build/gcc/gcj -B/home/tromey/gnu/Trunk/build/i686-pc-linux-gnu/libjava/ -B/home/tromey/gnu/Trunk/build/gcc/ --encoding=UTF-8 -Wno-deprecated -fclasspath= -fbootclasspath=/home/tromey/gnu/Trunk/build/i686-pc-linux-gnu/libjava -ffloat-store -g -MD -MT java/lang/Class.lo -MF java/lang/Class.d -c ../../../gcc/libjava/java/lang/Class.java -fPIC -o java/lang/.libs/Class.o
java/lang/Class.lo:0: fatal error: can't open java/lang/Class.lo: No such file or directory
compilation terminated.


I suspect one of the recent option processing changes in gcc.
It appears that gcc thinks that the argument to -MT is an input file
of some sort.
