[oe] Recent problems with host library leakage into the build

[Stefan Schmidt]

Hello.

I just stumbled over two problems in the testing-release bracnh that have wrong
path to the libs while linking the binaries and fail due to ld not being happy
to link x86_64 with ARM :)

openjdk-6_6b18-1.8:

| arm-angstrom-linux-gnueabi-gcc -march=armv7-a -mtune=cortex-a8 -mfpu=neon
-mfloat-abi=softfp -mthumb-interwork -mno-thumb
--sysroot=/home/stefan/oe-dev/build/tmp/sysroots/armv7a-angstrom-linux-gnueabi
-shared  -Wl,--whole-archive ../../src/fdlibm/.libs/libfdlibm.a
../../src/mm/.libs/libmm.a ../../src/native/.libs/libnative.a
../../src/threads/.libs/libthreads.a ../../src/toolbox/.libs/libtoolbox.a
../../src/vm/.libs/libvm.a ../../src/vmcore/.libs/libvmcore.a
-Wl,--no-whole-archive  -L/usr/lib -lz -lpthread -ldl  -march=armv7-a
-mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -mthumb-interwork -mno-thumb
-Wl,--version-script=../../contrib/mapfile-vers-product -Wl,-O1
-Wl,--hash-style=gnu -Wl,-soname -Wl,libjvm.so -o .libs/libjvm.so
| /usr/lib/libz.so: file not recognized: File format not recognized
| collect2: ld returned 1 exit status
| libtool: install: error: relink `libjvm.la' with the above command before
installing it

I imagine that I have seen something similar for freetype, but I can't reproduce
it right now.

Anyone an idea what causes this? If not I'm going to bisect it. Its just
painful as openjdk needs tons of time to build.
