        Description

        Use DWARF debug symbols for Linux 32-bit builds instead of STABS.

        The main arguments for using DWARF are:
          - DWARF provides a superior debugging experience compared to STABS.
          - STABS support in GCC/GDB is in maintenance mode [0].
          - Due to Solaris 32-bit support being dropped, we can now justify the
            size increase of using DWARF (see below for details).
          - External tools (e.g. perf on Linux) often understands DWARF but not
            STABS.
          - Compilation on 32-bit Linux can make use of precompiled headers.
