151# the multilib dirs and multilib os dirs. Only problem here is we are
152# cross building a native compiler so we cannot actually run xgcc.
153# We get around this by substituting our cross-compiler here for xgcc,
154# by rights it should have the same specs and produce the expected results
155#
156# NOTE: with gcc-4.1 onwards we can just set GCC_FOR_TARGET to our cross-compiler
157#       and be done with the shenannigans

181# When cross-building a target native compiler we run into big issues
182# when determining assembler and linker features required for tls support,
183# ( not to mention which nm, objdump et al to use ) during the configures
184# triggered by make.
185#
186# Gcc's configury does not take into account the fact that when cross
187# building the target native compiler we are _still_ actually cross-compiling.
188# As far as it is concerned during the final configure fragment host = target,
189# it doesn't check whether host = build.
190#
191# It then performs its checks for binutils components as if this was a standard
192# host native build.
193#
194# If a target native binutils was installed before attempting to build gcc
195# it will try to use the created ld, as etc under ${TGT_TOOLS}
196# This obviously will not work, they will not run on the host.
197#
198# If the target native binutils hasn't been built yet it will use the
199# as ld et al from the _build_ host.
200# This quite frankly sucks rocks.
201#

203# cross-tools for configure checks if host = target and host != build
