Bug#890092: i386 libgcc and libstdc++ illegal instruction on i586

[Gianluigi Tiesi <sherpya@netfarm.it>]

Source: gcc-8
Severity: important

I don't known if debian i386 supposed to drop i586 cpu
(I already had problems with the kernel) but
gcc-8 build of libgcc and libstd++ are not working on my geode
I get illegal instructions while executing e.g. apt,
revering back both libs to gcc7, made apt work again.
