But libssp_init only processes the first one; see how they're
handled for libmudflap, for example, to add all of them to
LD_LIBRARY_PATH.

This uses the 32-bit library for -m32, and adds it to LD_LIBRARY_PATH

This uses the 32-bit library for the default and adds the 32-bit
library to LD_LIBRARY_PATH.
