Compiling llvm and mlir as shared objects linked to xla

[Guillermo-Callaghan]

I would like to compile the mlir and llvm part of the project as shared
objects instead of having a binary that is mostly static. However, I am new to
bazel and I couldn't find a way to do it.

Setting the attribute linkstatic = False, to the mlir-hlo-opt rule target
creates a binary with many dynamic libraries (around 315).

I am looking to end with something like this, with libLLVM.so and libMLIR.so
dynamically link:

ldd bazel-bin/xla/mlir_hlo/mlir-hlo-opt
        libLLVM.so      => /myllvm/libLLVM.so.0 (0x0000ffffbxxxxxx)
        libMLIR.so      => /mymlir/libMLIR.so.0 (0x0000ffffbxxxxxx)
        libdl.so.2      => /lib64/libdl.so.2 (0x0000ffffbb256000)
        libm.so.6       => /lib64/libm.so.6 (0x0000ffffbb185000)
        libstdc++.so.6  => /lib64/libstdc++.so.6 (0x0000ffffb0d1b000)
        libgcc_s.so.1   => /lib64/libgcc_s.so.1 (0x0000ffffb0cf6000)
        libpthread.so.0 => /lib64/libpthread.so.0 (0x0000ffffbaf48000)
        libc.so.6       => /lib64/libc.so.6 (0x0000ffffbadb2000)
        linux-vdso.so.1 (0x0000ffffbb2b5000)
        /lib/ld-linux-aarch64.so.1 (0x0000ffffbb277000)

Can this be done?
