Building gcc 11.2 with jit support requires GMP, MPFR, MPC, ISL recompiled with -fPIC

Question

I'm on a CentOS 7 Linux system where I don't have the root access. So I have to build gcc from source. I want to build gcc 11.2 with the jit support. I invoked contrib/download_prerequisites for GMP, MPFR, MPC and ISL. Then from a build directory I configured gcc using

../gcc-11.2.0/configure --prefix=/some/path --enable-bootstrap --enable-shared \
  --enable-host-shared --enable-threads=posix --enable-languages=c,c++,jit \
  --disable-multilib

then I hit make.

It failed with ld errors asking me to recompile libisl.a, libmpc.a, libmpfr.a, libgmp.a with -fPIC. Right before these errors I saw lots of jit related outputs. I assume jit is behind all of this?

Then I tried adding CFLAGS=-fPIC to the above configure command as ../gcc-11.2.0/configure CFLAGS=-fPIC *rest_of_the_options_above*. The same ld errors were emitted.

I'm aware that those dependencies each has --with-pic option to their own configure. But I'm wondering if there is a way to have gcc invoke that for me? If not, does it mean that to build gcc with jit support, one has to build the four dependencies manually with --with-pic? Thanks.
