Recently, I build th binutils2.20.51 from the cvs. The build process broken cause after I execute the configuration script, it hang on "checking whether a statically linked program can dlopen itself".
However, It's OK in ArchLinux. So I suppose it maybe a configuration problem or system bug.
in config.log:
......
configure:11245: checking for dlopen in -ldl
configure:11270: gcc -o conftest -O2 -fomit-frame-pointer -s -minline-stringops-dynamically conftest.c -ldl >&5

configure:11587: $? = 0(HANG AT HERE)
the source file of the hung program is in the attachment.
build it with gcc conftest.c -Wl,--export-dynamic -static -o conftest
Execute it by
./conftest
and it will hang up,and the CPU is very very busy.
Why this happen on ubuntu but archlinux is ok. Is there a solution?
