--- Comment #1 from Gustavo Walbon <gustavowalbon at gmail dot com> ---
I have seeing a bunch of packages failing because this warning of linker when I
build several packages on Alpine for PowerPc.
I have a alpine container running on a PowerPC 8, and I rebuilt the all gcc
packages with the flags --with-long-double-64 and --without-long-double-128 to
avoid this error, but that still happens
I used the same code as Tulio to reproduce that warning.
~ $ gcc -v
Using built-in specs.
