[Qemu-devel] [PATCH 02/12] configure: Support empty target list (--target-list=) |
Date: |

From: Stefan Weil <address@hidden>
Specifying an empty target list with --target-list= is shorter
than specifying --disable-user --disable-system.
Both variants should give the same result: no targets at all.
This modification implements that feature.
It uses a trick which works with POSIX compliant shells to test whether
target_list is undefined (=> default targets) or empty (=> no targets).
