Merge remote-tracking branch 'remotes/bonzini/configure' into staging
* remotes/bonzini/configure: rules.mak: Rewrite unnest-vars configure: unset interfering variables configure: duplicate/incorrect order of -lrt libcacard: improve documentation libcacard: actually use symbols file libcacard: replace qemu thread primitives with glib ones vscclient: use glib thread primitives not qemu glib-compat.h: add new thread API emulation on top of pre-2.31 API Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
