target/hexagon: don't look for static glib

When cross compiling QEMU configured with --static, I've been getting
configure errors like the following:

    Build-time dependency glib-2.0 found: NO

    ../target/hexagon/meson.build:303:15: ERROR: Dependency lookup for glib-2.0 with method 'pkgconfig' failed: Could not generate libs for glib-2.0:
    Package libpcre2-8 was not found in the pkg-config search path.
    Perhaps you should add the directory containing `libpcre2-8.pc'
    to the PKG_CONFIG_PATH environment variable
    Package 'libpcre2-8', required by 'glib-2.0', not found

This happens because --static sets the prefer_static Meson option, but
my build machine doesn't have a static libpcre2.  I don't think it
makes sense to insist that native dependencies are static, just
because I want the non-native QEMU binaries to be static.
