filament: ubuntu 20.04 problem with compilation

Describe the bug A clear and concise description of what the bug is. So I compile, and I have the following:

/usr/bin/ld: /usr/bin/../lib/gcc/x86_64-linux-gnu/9/../../../x86_64-linux-gnu/libc++.a(algorithm.cpp.o): relocation R_X86_64_32 against `.bss' can not be used when making a shared object; recompile with -fPIC

clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [third_party/spirv-tools/source/CMakeFiles/SPIRV-Tools-shared.dir/build.make:1081: third_party/spirv-tools/source/libSPIRV-Tools-shared.so] Error 1
make[1]: *** [CMakeFiles/Makefile2:3796: third_party/spirv-tools/source/CMakeFiles/SPIRV-Tools-shared.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....

After this:

cmake -DCMAKE_CXX_FLAGS="-fPIC" -DCMAKE_C_FLAGS="-fPIC" ..
make

and still the same error
