+Configure script fix for glib version
+Description of problem:
+Script "configure" uses "pkg-config" directly, at line 2420: https://gitlab.com/qemu-project/qemu/-/blob/f9f0e6173e1d570847930abfe2b4560c7b6a964a/configure#L2420
+
+Because of it, GLIB_VERSION in "config-host.mak" can be taken from host system, under some circumstances (if PKG_CONFIG_PATH is not defined).
+
+In case of cross-compilation, "**$pkg_config**" should be used instead of "pkg-config", to use pkg-config from cross-compilation toolchain and to take GLIB_VERSION of cross-compiled glib (as it is **correctly used at line 1476**: https://gitlab.com/qemu-project/qemu/-/blob/f9f0e6173e1d570847930abfe2b4560c7b6a964a/configure#L1476 ).
+Steps to reproduce:
+1. Do not define PKG_CONFIG_PATH environment variable, use PKG_CONFIG variable instead.
+2. Try to ./configure with cross-compiled glib.
+3. GLIB_VERSION in config-host.mak will be from host glib.

+P.s. Sorry for posting the patch here, GitLab requires signing with a key to push the commit, it's too complicated to post 2-bytes fix.
