Subject: Explicitly test command -v host output before trying host command.
X-Git-Tag: svn/VALGRIND_3_12_0~242
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=11e3a4824db40c48121c4fd9e68a1b42c4162c3d;p=thirdparty%2Fvalgrind.git

Explicitly test command -v host output before trying host command.

We have to explicitly test command -v host worked otherwise on systems
that do not have 'host' installed will return error code 127 and stop
testing. This is because vg_regtest uses '/bin/sh -c' to execute the
prereq command. Found by Petar Jovanovic.
