oddity in build log

[Tom Tromey]

I've noticed recently in my build logs that a particular invocation of
ld/genscripts.sh now prints the environment:

    LIB_PATH='' /bin/sh ../../binutils-gdb/ld/genscripts.sh "../../binutils-gdb/ld" "/home/tromey/gnu/gdb/devel/install/lib" "/home/tromey/gnu/gdb/devel/install" "/home/tromey/gnu/gdb/devel/install" x86_64-unknown-linux-gnu x86_64-unknown-linux-gnu x86_64-unknown-linux-gnu "elf_x86_64 elf_i386 elf32_x86_64 elf_l1om elf_k1om" "/usr/local/lib /lib /usr/lib" no yes nds32elf ""
    ADA_CFLAGS=
    AR=ar
    ARCH=nds32
    AR_FLAGS=rc
    [... 200+ more lines...]

I didn't see this before (it triggers the error recognition regexp in
emacs, so I probably would have noticed), so probably some recent change
introduced a shell buglet here.

thanks,
Tom
