[Qemu-devel] [PATCH v2 1/2] ./configure: request pkg-config to provide private libs when static linking

[Sergei Trofimovich <slyfox@inbox.ru>]

From: Sergei Trofimovich <slyfox@gentoo.org>

Added wrapper around pkg-config to allow:
- safe options injection via ${QEMU_PKG_CONFIG_FLAGS}
- spaces in path to pkg-config

Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
