Pavel Chupin a567a8e4bd x86_64: Update Makefiles for x86_64 targets and add symlinks

manually optimized and .s versions released.

# libgcc.a are made static to libdl.so. This in turn ensures that libraries that
# a) pull symbols from libgcc.a and b) depend on libdl.so will not rely on libdl.so
# to provide those symbols, but will instead pull them from libgcc.a. Specifically,
# we use this property to make sure libc.so has its own copy of the code from
# libgcc.a it uses.
