Subject: [PATCH] Fix symlink path for libgcc

The symlink for libgcc_so.1.0 is made to point to libunwind.so
which is functionally correct but it fails some linux distro packaging
complain because libunwind.so is made part of -dev package but
libgcc_so.1.0 ends up in the real package, and creates an unneeded
package -> dev dependency

create the symlink to point to libunwind.so.1 instead then the boundaries
of packaging are not crossed and all is well.
