Naturally:

dependency_libs='
-L/home/bfriesen/src/gnu/gcc-3.4.0-build/sparc-sun-solaris2.9/libstdc++-v3/src
-L/home/bfriesen/src/gnu/gcc-3.4.0-build/sparc-sun-solaris2.9/libstdc++-v3/src/.libs
-lm -lm -lm -L/home/bfriesen/src/gnu/gcc-3.4.0-build/gcc
-L/usr/ccs/bin -L/usr/ccs /lib -L/usr/local/lib -lgcc_s -lgcc_s -lm
-lgcc_s -lgcc_s'

While it is true that this bug is specific to the libraries built with
GCC, since many systems use GCC, this bug is inherited by libtool.
