commit 02ce382cd323097f9d02fbf91e0a3f59ebcd3d30
Author: Sandra Loosemore <sandra@codesourcery.com>
Date: Wed Feb 12 12:20:15 2020 -0800
Use a non-empty test program to test ability to link.
On bare-metal targets, I/O support is typically provided by a BSP and
requires a linker script and/or hosting library to be specified on the
linker command line. Linking an empty program with the default linker
script may succeed, however, which confuses libstdc++ configuration
when programs that probe for the presence of various I/O features fail
with link errors.
