Prepare build system for building multiple versions of the agent library.
src-disl-agent/Makefile: use 'ld' instead of 'gcc' for linking. src-disl-agent/Makefile: avoid -flto for normal builds, may be broken on old compilers found in Ubuntu. src-disl-agent/Makefile: support building 32-bit and 64-bit versions of the agent library. build.xml: adjusted to look for the library in os-arch-specific directory.
