Subject: Prevent unwanted linkage to -lhogweed
X-Git-Tag: gnutls_3_5_7~25
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b0a103cb56d254d167a963bd955c42acb3155ce7;p=thirdparty%2Fgnutls.git

Prevent unwanted linkage to -lhogweed

Specify action-if-found for AC_CHECK_LIB when checking for !SuiteB
curves to keep autoconf from adding -lhogweed to LIBS. This caused
linkage of e.g. openssl wrapper and C++ library to -lhogweed. The issue
only shows up if --disable-libdane is specified, since the dane autoconf
test resets LIBS.
