Subject: Fix -Ttext-segment configure check.
X-Git-Tag: svn/VALGRIND_3_9_0~313
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fc14d93e0045f9a78e69ef3ff1dd545c50a23c89;p=thirdparty%2Fvalgrind.git

Fix -Ttext-segment configure check.

Explicitly test together with -static -nodefaultlibs -nostartfiles to mimic
what the tools linking script does. At least on s390 the test might fail for
a non-static AC_LINK, while it does work when using those other flags too.
