I have my sysrooted toolchain sitting in /home/alan/toolchain/, so
there is /home/alan/toolchain/lib/libc.so.6 and
/home/alan/toolchain/lib/ld.so.1.  Someone then passes -L/usr/lib
-L/lib to gcc, resulting in /lib/libc.so.6 being found rather than my
sysrooted version.  The DT_NEEDED search finds
/home/alan/toolchain/lib/ld.so.1 to meet the libc dependency, but
ld.so and libc.so are then from different versions of glibc.  Boom.

Anyway, killing the -L search is probably using too big a hammer.
I'll try something different.
