NetBSD and pkgsrc have been using an empty vendor string since the
mid-'90s, such as x86_64--netbsd. pkgsrc has been carrying around a
workaround just the guile build for a long time. (Before that,
NetBSD omitted the vendor altogether, so if x86_64 existed then it
might have been `x86_64-netbsd', but that caused more problems.)
This change makes Guile accept an empty vendor string so workarounds
are no longer necessary.
* module/system/base/target.scm (validate-target): Allow empty vendor
string in GNU target triplets.
* test-suite/tests/cross-compilation.test ("cross-compilation"): Add
tests for "x86_64--netbsd".
