[gentoo-user] -flto set for simh-3.9.0-r1 let gcc fail on my Beaglebone Black

Hi,

for app-emulation/sim-3.9.0-r1 (in opposite to the previous version)
-flto was set.
But there is no LOT-support in gcc, which is delivered with the stage3
build of gentoo for ARMv7 (Beaglebone/black).

I already tried do set new CFLAGS via /etc/portage/env/nolto.conf:

    beagleboneblack:portage/package.env>cat simh 
    app-emulation/simh no-lto.conf

and and an according file in /etc/porttage/package.env:

    beagleboneblack:portage/package.env>cat simh 
    app-emulation/simh no-lto.conf

but this does not have any effect.

What is the least intrusive, most compatible way for me to disable the
use of -flto in this ebuild?

Thank you very much in advance for any help!
Best regards,
mcc
