Subject: Build system fixes so as to temporarily disable the GDBserver on
X-Git-Tag: svn/VALGRIND_3_7_0~352
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=30d2b29153869f637ea8527256f93b79a2be302e;p=thirdparty%2Fvalgrind.git

Build system fixes so as to temporarily disable the GDBserver on
Android.  Making that work will require a bit of extra effort due to
minor glibc-vs-bionic differences.
