[release-branch.go1.17] cmd/link: do not use GO_LDSO when cross compile

Browse Source 
GO_LDSO is a setting that is set when the toolchain is build. It
only makes sense to use it on the host platform. Do not use it
when targetting a different platform.

In the past it was not a problem as GO_LDSO was almost always
unset. Now, with CL 301989 it is almost always set (maybe we want
to revisit it).

Updates #47760.
Fixes #47782.
