Motivation

From forums.swift.org:

The armv7em-none-none-eabi/libswiftUnicodeDataTables.a does not link when using the Playdate SDK.

The Playdate SDK link-map disables the following symbols:

__exidx_end
__exidx_start

These appear to be ARM exceptions which were added to swiftUnicodeDataTables through libunwind.

Proposed solution

Make a version of swiftUnicodeDataTables with --disable-libunwind-exceptions
