eclass/toolchain.eclass: disable libstdcxx-time for bare metal
Historically Gentoo unconditionally sets --enable-libstdcxx-time=yes
to avoid --enable-libstdcxx-time=rt on linux targets, bug #411681
Unfortunately this conflicts with arm-none-eabi and other
bare-metal targets that don't provide enough plumbing
to support for POSIX timers.
This change ogerrides our default to --disable-libstdcxx-time
on *-elf and *-eabi targets.
Tested as:
$ crossdev --stage4 arm-none-eabi
