 The problem with this one is the following:

/home/test/test/output1/host/usr/bin/i686-pc-linux-gnu-ld -r -o src/library.o  src/library/getopt.o src/library/gettext.o
/home/test/test/output1/host/usr/bin/i686-pc-linux-gnu-ld: i386:x86-64 architecture of input file `src/library/gettext.o' is incompatible with i386 output

 This is because the Sourcery toolchain is a multilib toolchain that can
generate two different emulations (elf_i386 and elf_x86_64). gcc adds the
"-m elf_x86_64" option to ld, but of course there is no way for configure
or whatever to discover that this is necessary.

 There are probably other packages that suffer the same problem - in fact,
any package that uses $(TARGET_LD) will most likely suffer from it.

 I'm not sure how to solve this. We could set TARGET_LD to 
"$(TARGET_CROSS)ld -m elf_x86_64" for the specific case of x86_64 external
toolchains (it probably doesn't hurt to add the default emulation 
explicitly). But there may be other external toolchains with the same
problem - none of the current ones, at first sight, but who knows what the
future brings.

 So what do you think?
