Solve the host tools relying on host libraries problem
We build host tools installed in $(HOST_DIR)/usr/bin, and some of them
rely on host libraries in $(HOST_DIR)/usr/lib. So when these host
tools are executed, they need to find the host libraries, which are
not installed in a default location.
In c1b6242fdcf2cff7ebf09fec4cc1be58963e8427 we tried to use
LD_LIBRARY_PATH when building target packages to solve this
problem. Unfortunately, LD_LIBRARY_PATH is not only used to find
libraries at run-time, but also at compile time. So it leads the build
of some packages, such as icu, to fail.
Therefore, in 0d1830b07db4ebfd14e77a258de6fb391e57e960, we reverted
the LD_LIBRARY_PATH idea.
The other option to solve this problem was to hardcode a RPATH value
in the host binaries that would reference the location of host
libraries. We added this -Wl,-rpath option to HOST_CFLAGS in
6b939d40f6a29a43277566adc9d4312d49cb3abf. Unfortunately, this caused
problems when building binutils, as reported in bug 1789 so this
change was reverted in e1a7d916e9eeaa215551740de40c055130d6c073.
Then, we tried to use -Wl,-rpath in HOST_LDFLAGS, but it was causing
problems with fakeroot not recognizing 'ld' as the GNU linker, since
the -Wl,-rpath cannot be understood by 'ld' directly, only by 'gcc'.
This commit is a new attempt at using HOST_LDFLAGS, but in this case
we modified the definition of HOST_LD to *not* contain
HOST_LDFLAGS. LDFLAGS are being set separatly. It solved the fakeroot
issue and was tested against nearly 300 packages of Buildroot.
