[PATCH] tools: ynl: build archives with $(AR)

[PATCH] tools: ynl: build archives with $(AR)

[Greg Thelen]

Use $(AR) to allow build system to override the archiver tool (e.g.,
when cross-compiling for a different architecture) by setting the AR
environment variable.

GNU Make defaults AR to ar, so this change will not break existing build
environments that do not explicitly set AR.

Fixes: 07c3cc51a085 ("tools: net: package libynl for use in selftests")
Fixes: 86878f14d71a ("tools: ynl: user space helpers")
