Subject: [PATCH] BUG/MINOR: build: handle whitespaces in wc -l output

Certain implementations (for example ksh/OpenBSD) prefix the
'wc -l' output with whitespaces. This breaks the build since
689e4d733 ("BUILD: simplify the date and version retrieval in
the makefile").

Fix this by piping the wc output into tr -dc '0-9'.

Workaround is to build with IGNOREGIT=1.

HAProxy-1.4 is affected as well.
