Subject: configure.ac: Only check for things we actually use.
X-Git-Tag: libsigrok-0.3.0~173
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=7d4874c1b63c169d1847e93c0d221a16d662dd53;p=libsigrok.git

configure.ac: Only check for things we actually use.

Drop checks where we don't use the result (yet). We might bring back
some of those once we start actually using the result in the code.
