PR466 & library names

If you've recently updated and noticed that the linkers are producing:
"Cannot find library -lc", you need to rebuild your runtime libraries
(cd runtime ; make clean ; make install). Fixing PR466 caused the names
of the libraries built/installed and sought by the linker to change. We
previously installed libXYZ.bc because it was a bytecode file. We now
install libXYZ.a which is an archive library with bytecode file
contents. Subtle difference, but it allows "gccld -lc -lc" and the
dependent libraries feature to work.
