[Qemu-devel] [PATCH] Fix some configure/Makefile weirdness

[Thiemo Seufer <ths@networkno.de>]

Hello All,

the appended patch allows for propagating CFLAGS and LDFLAGS to the host
Makefile. This reactivates the (undocumented) --extra-cflags= and
--extra-ldflags= options of configure which are currently NOPs.
It also removes the CFLAGS=-O2 default from configure since it is
already hardcoded in Makefile and Makefile.target.

Comments?


Thiemo
