[tools][remarks-shlib] Don't build without PIC

A build on `sparcv9-sun-solaris2.11` with `-DLLVM_ENABLE_PIC=Off` failed
linking ``:

  [27/2297] Linking CXX shared library lib/
  FAILED: lib/
  ld: fatal: relocation error: R_SPARC_H44: file lib/libLLVMRemarks.a(Remark.cpp.o): symbol _ZTVN4llvm18raw_string_ostreamE: invalid shared object relocation type: ABS44 code model unsupported

On Solaris/sparcv9 as on many other targets you cannot link non-PIC objects
into a shared object.

The following patch avoids this by not building the library with PIC.  It
allowed the build to complete and `ninja check-all` showed no errors.
