[Qemu-devel] [PATCH 2/2] configure: fix detection for SDL libs when static linking

["Yann E. MORIN" <yann.morin.1998@free.fr>]

Currently, configure checks for SDL libs either with pkg-config (the
default), or with sdl-config (as a fallback).

But sdl-config does not have the same set of options as pkg-config:
  - to check for shared libs, both use the option: --libs
  - to check for static libs:
    - pkg-config uses: --static --libs
    - sdl-config uses: --static-libs

Fix that by using the previously introduced $QEMU_XXX_CONFIG_LIBS_FLAGS
variable, the way it was done previously for cURL.

Also, simplify the code-path for checking for SDL libs with a single,
non-conditional call to $sdlconfig, which is either pkg-config or
sdl-config, as checked just above.
