.so: undefined reference to `ebx' (lizardfs @ i686)

[Mateusz Korniak]

Any hint why build of lizarfs fails on i686 with:

cd /home/users/matkor/rpm/BUILD/lizardfs-v.3.9.4/build/src/admin && 
/usr/bin/cmake -E cmake_link_script CMakeFiles/lizardfs-admin.dir/link.txt --
verbose=1
/usr/bin/i686-pld-linux-g++    -pipe -std=c++0x -pthread -Wall -Wextra -fwrapv 
-pedantic -O3 -DNDEBUG -O3 -DNDEBUG -g   CMakeFiles/lizardfs-
admin.dir/main.cc.o  -o lizardfs-admin -rdynamic liblizardfs-admin-lib.so 
../common/libmfscommon.so ../../external/libcrcutil.so -lz -lrt -Wl,-
rpath,/home/users/matkor/rpm/BUILD/lizardfs-
v.3.9.4/build/src/admin:/home/users/matkor/rpm/BUILD/lizardfs-
v.3.9.4/build/src/common:/home/users/matkor/rpm/BUILD/lizardfs-
v.3.9.4/build/external: 
../../external/libcrcutil.so: undefined reference to `ebx'


while built with original set of flags [1] builds OK ?

cmake .. -DCMAKE_BUILD_TYPE=Release
make
