Incorporate multi-binary build support in check-mail Makefile to other projects

[atc0005]

Sample snippets from that Makefile:

# Space-separated list of cmd/BINARY_NAME directories to build
WHAT 					= check_imap_mailbox

.PHONY: linux
## linux: generates assets for Linux distros
linux:
	@echo "Building release assets for linux ..."

	@for target in $(WHAT); do \
		mkdir -p $(OUTPUTDIR)/$$target && \
		echo "Building 386 binaries" && \
		env GOOS=linux GOARCH=386 $(BUILDCMD) -o $(OUTPUTDIR)/$$target/$$target-$(VERSION)-linux-386 ${PWD}/cmd/$$target && \
		echo "Building amd64 binaries" && \
		env GOOS=linux GOARCH=amd64 $(BUILDCMD) -o $(OUTPUTDIR)/$$target/$$target-$(VERSION)-linux-amd64 ${PWD}/cmd/$$target && \
		echo "Generating checksum files" && \
		$(CHECKSUMCMD) $(OUTPUTDIR)/$$target/$$target-$(VERSION)-linux-386 > $(OUTPUTDIR)/$$target/$$target-$(VERSION)-linux-386.sha256 && \
		$(CHECKSUMCMD) $(OUTPUTDIR)/$$target/$$target-$(VERSION)-linux-amd64 > $(OUTPUTDIR)/$$target/$$target-$(VERSION)-linux-amd64.sha256; \
	done

	@echo "Completed build tasks for linux"
