I'm setting LD_LIBRARY_PATH as follows, which seems to work:

LD_LIBRARY_PATH=$(find . -name "*.so" | sed 's,^\.,'`pwd`',; s,/[^/]*$,,; s,$,:,' | sort -u | sed '$s/://' | tr -d "\n"; echo ':'`pwd`/gcc)

but `terrible kludge' doesn't even begin to describe it.

(The sed tries to remove the filenames, canonicalize the paths, zap
unnecessary redundancy and colon-separate them. I could have used
basename and a loop but that would have been insufficiently ugly.)
