Subject: configure: duplicate/incorrect order of -lrt
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=18e588b197545412cad65f0b07e13c161cac4bea;p=qemu.git

configure: duplicate/incorrect order of -lrt

'-lrt' flag duplication/incorrect order
would cause 'undefined reference to clock_gettime' error during compilation time.

Before fix:
... -o qemu-bridge-helper qemu-bridge-helper.o    -lrt -pthread -lgthread-2.0 -lrt -lglib-2.0
After fix:
... -o qemu-bridge-helper qemu-bridge-helper.o    -pthread -lgthread-2.0 -lrt -lglib-2.0
