Subject: fix: Add CLASSPATH to autoconf precious variables
X-Git-Tag: v2.13.0-rc1~506
X-Git-Url: http://git.liburcu.org/?p=lttng-ust.git;a=commitdiff_plain;h=b1035e615d2283d13fc7598e64a9e82f068a37c8

fix: Add CLASSPATH to autoconf precious variables

This will record the value of CLASSPATH in the autoconf cache and ensure
it's used when calling make even if it's not exported to the
environment.
