[fedora-arm] Problems building glibc

Hello, I'm just thinking maybe the toolchain is broken there. I'm using a sheevaplug. I want to build glibc. I get the same problem also with eglibc. glibc's configure tries to check if "-fexceptions" works in gcc. So it issues this test: cat > conftest.c <<\EOF _start () {} int __eh_pc; __throw () {} EOF gcc -nostdlib -nostartfiles -fexceptions conftest Which ends this way: /tmp/nix-build-dyvs01kjvp1k9ja2krq5xfjgcj55sgm7-eglibc-2.9.drv-0/ccCmXD2v.o:(.ARM.exidx+0x0): undefined reference to `__aeabi_unwind_cpp_pr0' This symbol is in libgcc_s. This file is not included in the linking when using -nostdlib. I test the same in my i686, and all works. I think it doesn't need anything from libgcc_s for the tests in conftest.c. Exceptions are needed for nptl support in glibc, and I think glibc won't compile well without nptl (trying to disable it, I get errors about TLS, which also I could not manage to avoid). I think I should point to having nptl support, as it's there for arm. Trying to add "-lgcc_s" in LDFLAGS doesn't help, because this breaks the tests for "-static" compilations. libgcc_s is in fedora only as shared library. How should I build glibc or eglibc? Can I check the build scripts for fedora's glibc somewhere? Regards, Lluís.
