Redo checks for g-prefixed alternatives after potentially having asked to install missing applications. Fixed linux and glibc builds for FreeBSD (including the old issue which previously broke glibc's write and others in the resulting system, apparently caused by differences between BSD and GNU sed) Disable gcc plugins unless building on GNU+Linux since a buildtime tool fails to compile natively. Fixed an issue with sed thinking re_compile wasn't working due to not being able to test it when crosscompiling. Disable gawk extensions which would otherwise fail when crosscompiling. Avoid the linux-specific __user macro in util-linux, for some reason it is not substituted when crosscompiling. Work around linux assuming we want a 64-bit kernel despite using ARCH=x86 (not x86_64) if the buildhost happens to be 64-bit, may have been introduced with the switch to 3.11. Do not build binutils in a separate build-directory or it will depend on texinfo to regenerate documentation, seems to have been introduced with the update to 2.23.2. Disable static linking to libgcc when building the toolchain gcc since it caused errors in at least one case, I hope the dynamic linking won't cause problems elsewhere.
