This prevents the building +of a package in GOPATH for later staging into GOROOT. + +This patch adds support for the environment variable +GOPATH_OMIT_IN_ACTIONID. If present, path name +embedding is disabled. + +Second, if cgo is enabled, the build ID for cgo-related +packages will include the current value of the environment +variables for invoking the compiler (CC, CXX, FC) and +any CGO_xxFLAGS variables. Only if the settings used +during a compilation exactly match, character for character, +the values used for compiling runtime/cgo or any other +cgo-enabled package being imported, will the tool +decide that the imported package is up-to-date. + +This is done to help ensure correctness, but is overly +simplistic and effectively prevents the reuse of built +artifacts that use cgo (or shared runtime, which includes +runtime/cgo). + +This patch filters out all compiler flags except those +beginning with '-m'.
