[Vagrant Cascadian]

Source: nis
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Various binaries shipped in nis are build differently when the build
path varies:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/nis.html

  /usr/bin/ypcat
  GNU··0x00000014»  NT_GNU_BUILD_ID·(unique·build·ID·bitstring)» Build·ID:·dedd8715faeef72ca4c5130f43d08f8df595b39a
  vs. 
  GNU 0x00000014»  NT_GNU_BUILD_ID·(unique·build·ID·bitstring)»  Build·ID:·5dba43813c061ce956ac0741ae4bb981fc1eaa4e

The attached patch fixes this by adding -ffile-prefix-map to CFLAGS.
