Subject: tests/autotest.at: don’t use suffix rules to generate executables
X-Git-Tag: v2.69c~73
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7c08375081545e1eaf96461319ffec0a02e9f959;p=thirdparty%2Fautoconf.git

tests/autotest.at: don’t use suffix rules to generate executables

In two tests, when @EXEEXT@ is empty, we were generating Makefiles
containing suffix rules with only one explicit suffix, e.g.

    .o:
        $(CC) -o $@ $^

Solaris 10’s ‘dmake’ does not understand this as a rule to create
‘foo’ from ‘foo.o’.  That’s not the point of the tests, so use
ordinary per-rule commands to link the executables in these tests
instead.

Partially addresses #110267.
