This reverts commit aa79cf2708.
Reason for revert: -fPIC is needed in more places than the CL adds it to, see CI builds at https://ci.chromium.org/ui/p/dart-internal/builders/ci/dart-sdk-linux-riscv64-dev/405/overview
Original change's description:
> [build, vm] Access TLS with less code.
>
> - Avoid TLS initialization checks by using inline initialization.
> - Avoid global offset table indirection by reducing -fPIC to -fPIE.
>
> out/ReleaseXARM64/exe.stripped/dart_precompiled_runtime
> 11137992 -> 11274776 (-1.21%)
>
> We still need -fPIC in some places because we build a few shared libraries for FFI, so copy some of Fuchsia's GN setup to use -fPIE or -fPIC as appropriate.
>
> TEST=ci
