           Summary: Allow use of older external toolchains without sysroot
                    support
           Product: buildroot
           Version: 2010.02
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: cls at seawood.org
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


I'm using buildroot to create packages that are binary compatible with the
default rootfs provides in my Patriot Corza NAS.  As such, I'm unable to
upgrade to a newer toolchain that supports --sysroot.

The attached patch updates package/Makefile.in, ext-tool.mk and various package
.mks to allow buildroot to be built with an external toolchain that does not
use --sysroot (gcc-3.4.6, in my case).  The use of --sysroot is now controlled
by the BR2_TOOLCHAIN_EXTERNAL_SYSROOT option.  

Most of the other changes just involve passing TARGET_CONFIGURE_ENV to the
configure or make calls for each package.

There's also a change to override the broken getline detection in sed when
using an external glibc toolchain.
