    4 Initial Package Version: 3.4.1 (problem exists through 3.3 series)
    5 Upstream Status: Unknown
    6 Description: There are issues with configure when attempting to cross-compile
    7 a native gcc for target. During the last stage of make configure-host,
    8 where host = target, the configury doesn't check if host != build.
    9 Therefore it assumes that the build is a native build and performs
    10 binutils feature checks using either
    11 a) what the native compiler we are building would normally use.
    12 If a target-native binutils has already been built with the same
    13 prefix, this is the binutils which is used which of course will not
    14 work on host
    15 b) the host os's assembler/linker/nm/as
    16 which leads to bogus results.
    17 This patch fixes this behaviour, so that if host = target and
    18 host != build the cross tools will be used for feature checks.
