configure: preserve various environment variables in config.status
The config.status script is auto-generated by configure upon
completion. The intention is that config.status can be later invoked by
the developer directly, or by make indirectly, to re-detect the same
environment that configure originally used.

The current config.status script, however, only contains a record of the
command line arguments to configure. Various environment variables have
an effect on what configure will find. In particular PKG_CONFIG_LIBDIR &
PKG_CONFIG_PATH vars will affect what libraries pkg-config finds. The
PATH var will affect what toolchain binaries and XXXX-config scripts are
found. The LD_LIBRARY_PATH var will affect what libraries are
found. Most commands have env variables that will override the name/path
of the default version configure finds.

All these key env variables should be recorded in the config.status script.

Autoconf would also preserve CFLAGS, LDFLAGS, LIBS, CPPFLAGS, but QEMU
deals with those differently, expecting extra flags to be set using
configure args, rather than env variables. At the end of the script we
also don't have the original values of those env vars, as we modify them
during configure.
