Subject: configure: standardise include path
X-Git-Tag: v0.13.0~29
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=0195634254d90bac8517076685032ccffee75456;p=urcu.git

configure: standardise include path

Use the same include setup as our other projects, set the default
includes globally in configure.ac in AM_CPPFLAGS.

This is part of an effort to standardise our autotools setup across
project to simplify maintenance.
