[Bug bootstrap/30974] New: pdp11-dec-bsd will not successfully build

[hbent at cs dot oberlin dot edu]

I have an x86 NetBSD box and am attempting to build gcc for pdp11-dec-bsd.  I
have binutils 2.17 installed and configured for that target, and I have
includes and libraries from the latest revision of 2.11BSD.

configure is run as
../configure --target=pdp11-dec-bsd --enable-languages=c --with-gmp=/usr/pkg

Building gets to this point:

/usr/src/gcc/vax/./gcc/xgcc -B/usr/src/gcc/vax/./gcc/

The mis-generated assembly is at the very end of the file, and looks like this:

LC_0:
        0 /* short */
        0 /* short */
        0 /* short */
        0 /* short */
        .even
LC_1:
        0 /* short */
        0 /* short */

Unfortunately I have not the faintest clue as to what is happening here, or
why.  I would be happy to provide more details if someone can tell me what they
need.
