configure: pull ahead gcc-sysroot processing

Browse Source 
the sysroot flags need to be established even before setting up the
spec, because as soon as that happens, toolchain.prf will try to
determine the default paths and cache them.

this also fixes sysroot use in toolchain flag support tests, which run
(somewhat) independently from the toolchain setup.
