cmd/link: fail to build when using time/tzdata on ARM [1.15 backport]

[cherrymui]

(Creating manually as I don't think gopherbot would do this after it already created one.)

Please consider #44639 (fixed in 098504c for Go 1.17) for backport to the next 1.15 minor release.

This causes programs fail to build without easy workaround. It applies to 1.15 as well.

Change https://golang.org/cl/298030 mentions this issue: [release-branch.go1.15] cmd/link: generate trampoline for inter-dependent packages

[toothrot]

Approved. This is a serious issue with no workaround.

Closed by merging 7c88ae4 to release-branch.go1.15.
