[OE-core] [PATCH v8 3/9] go-1.8: add patch for set soname in ELF shared objects

[Otavio Salvador]

From: Matt Madison <matt at madison.systems>

The go link tool does not set the soname by default, which
prevents package.bbclass's shlibs processing from seeing
shared libraries built with go.

This patch passes appropriate options to go's linker and
the external linker to set the soname.
