xtensa-esp32s3-linux-uclibcfdpic: update settings

- disable default PIE because that setting subtly breaks the uclibc
  build: instead of compiling sources for the library it compiles them
  for the PIE, making all references to locally-defined global symbols
  bind locally. This generates different code that may not work
  correctly when linked into the shared library.
