    pcre2: fix host compilation of libselinux by enabling PIC
    
    libselinux-3.5 fails to compile in Fedora 38 container due to the
    following:
    
     cc -O2 -I/openwrt/staging_dir/host/include -I/openwrt/staging_dir/hostpkg/include -I/openwrt/staging_dir/target-x86_64_musl/host/include -I../include -D_GNU_SOURCE -DNO_ANDROID_BACKEND -DUSE_PCRE2 -DPCRE2_CODE_UNIT_WIDTH=8 -I/openwrt/staging_dir/hostpkg/include -L/openwrt/staging_dir/host/lib -L/openwrt/staging_dir/hostpkg/lib -L/openwrt/staging_dir/target-x86_64_musl/host/lib -Wl,-rpath=/openwrt/staging_dir/hostpkg/lib -shared -o libselinux.so.1 avc.lo avc_internal.lo avc_sidtab.lo  [...]
     /usr/bin/ld: /openwrt/staging_dir/hostpkg/lib/libpcre2-8.a(pcre2_compile.c.o): relocation R_X86_64_32S against symbol `_pcre2_ucd_stage1_8' can not be used when making a shared object; recompile with -fPIC
     /usr/bin/ld: failed to set dynamic section sizes: bad value
    
    So lets fix it by enabling build of host static library with the
    position independent code option enabled.
