Subject: Makefile: workaround an automake bug for "make check"
X-Git-Tag: v10.0.4~8^2~2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=3c5bc07973bc48c8cd8096cfbce15cbc8b39f41a;p=ceph.git

Makefile: workaround an automake bug for "make check"

override the automake variable of am__is_gnu_make. it is a workaround
for http://debbugs.gnu.org/cgi/bugreport.cgi?bug=18744. this bug was
fixed in automake 1.15, but automake 1.13 is supported. so we can not
just require 1.15 using `AM_INIT_AUTOMAKE`. this only happens when we
have lots of source files *and* we are using automake v1.14 or lower.

Fixes: #14723
