Subject: bootstrap: cater to autoconf 2.59
X-Git-Tag: v0.1~1240
X-Git-Url: http://erislabs.org.uk/gitweb/?a=commitdiff_plain;h=dd6b2d751b3c6ad417f6a4c48f2adb9d27cc59d2;p=gnulib.git

bootstrap: cater to autoconf 2.59

Autoconf didn't add --no-recursive until 2.59c, but gnulib supports
as far back as 2.59 for platforms like RHEL 5.

* build-aux/bootstrap (AUTORCONF): Work even when --no-recursive
is not available.
