configure: propagate --extra-cflags and --extra-ldflags to meson compile tests
Meson (intentionally) does not add QEMU_CFLAGS to cc.compiles/cc.links
tests, as they are supposed to be independent of the specific sets of
compilation flags used to build the programs. However, the user can
still use CFLAGS or the toolchain file's LANG_args/LANG_link_args option
to specify -I or -L options that apply to cc.compiles/cc.links as well.
This is also the intended use of configure's --extra-cflags,
--extra-cxxflags and --extra-ldflags options. For example, if
one has netmap's header in a nonstandard directory, up to commit
837b84b1c078bf3e909 it used to work fine to do:
.../configure --enable-netmap \
--extra-cflags=-I/path/to/netmap/sys
but since the test was converted to meson, this does not work anymore.
Pass these options to meson via the toolchain file instead of via
config-host.mak, since both have the same purpose.
