bug 1424323 - remove MOZ_AUTOMATION_UPLOAD_SYMBOLS from in-tree mozconfigs. r=rillian With all of our builds in Taskcluster now, we should never be uploading symbols from build tasks. Unfortunately Windows builds were still doing so. This patch removes MOZ_AUTOMATION_UPLOAD_SYMBOLS from all the in-tree mozconfigs and a few other places so that it should always default off (per moz-automation.mk). The rest of the uploadsymbols bits will be removed once Thunderbird fixes their automation. This patch was mostly autogenerated by running: rg --files-with-matches UPLOAD_SYMBOLS browser/config/mozconfigs/ mobile/android/config/mozconfigs/ | xargs sed -ri '/.*UPLOAD_SYMBOLS.*/d' sed -ri '/.*UPLOAD_SYMBOLS.*/d' build/unix/mozconfig.linux build/mozconfig.win-common build/macosx/local-mozconfig.common build/mozconfig.automation Then mobile/android/config/mozconfigs/common and taskcluster/scripts/builder/build-linux.sh were hand-edited.

BACKEND_GENERATION_SCRIPT ?= config.status

# A traditional rule would look like this:
#    backend.%:
#        @echo do stuff
#
# But with -j<n>, and multiple items in BUILD_BACKEND_FILES, the command would
# run multiple times in parallel.
#
# "Fortunately", make has some weird semantics for pattern rules: if there are
# multiple targets in a pattern rule and each of them is matched at most once,
# the command will only run once. So:
#     backend%RecursiveMakeBackend backend%FasterMakeBackend:
#         @echo do stuff
#     backend: backend.RecursiveMakeBackend backend.FasterMakeBackend
# would only execute the command once.
#
# Credit where due: http://stackoverflow.com/questions/2973445/gnu-makefile-rule-generating-a-few-targets-from-a-single-source-file/3077254#3077254
