Make treats tabs very differently from spaces at the beginning of a line,
so this test must use a tab instead of a space. This partially reverts
commit a0903134d2d60 (acinclude.m4: Expand tabs).
Without this commit, the build system never enables checking with sparse
because it never detects that GNU make "if" works.
