the new build system in binutils sets up custom LD_LIBRARY_PATHs which can cause
conflicts between the build and host. if you take binutils-2.17.50.0.17 and
build/install it with --enable-shared, your host binutils will all be linked
against libbfd-2.17.50.0.17.20070615.so:
$ readelf -d `which as` | grep NEEDED.*2.17
0x0000000000000001 (NEEDED) Shared library:
[libopcodes-2.17.50.0.17.20070615.so]
0x0000000000000001 (NEEDED) Shared library:
[libbfd-2.17.50.0.17.20070615.so]
but if you turn and and try to build it again, the LD_LIBRARY_PATH will be set
to your local build directories:
LD_LIBRARY_PATH=.../build/bfd/.libs:.../build/opcodes/.libs:....
and this makes your installed `as` very angry, especially when cross-compiling
as the local libraries are not targetting the same thing as your host libraries.
i cant think of any use for these LD_LIBRARY_PATHs as each binutils utility
includes a little libtool wrapper script which allows you to execute them in the
build dir and make sure the local shared libs are found and used properly ... so
`make check` would work OK ...
