toolchain.eclass: avoid libquadmath in stage1-gcc
libquadmath relies on libc presence (sqrt symbols).
When initial toolchain is bootstrapped libc is not
available yet.
The change disables libquadmath for bootstrap cases
when libc is not installed yet. gcc-stage2 still
uses platform defaults for libquadmath.
