toolchain: Allow external toolchains to specify libthread-db
We need to let external toolchains be able to specify the path and specification file to the libthread-db POSIX thread debugging shared libraries. This fixes GDB not being able to be installed because it is depending on libthread-db: Collected errors: * satisfy_dependencies_for: Cannot satisfy the following dependencies * for gdb: * libthread-db * * opkg_install_cmd: Cannot install package gdb.
