            Bug ID: 27290
           Summary: clang [built from source] on Mageia v6/Cauldron x86-64
                    fails with an error on the Hello World program

Hi all,

I previously reported a similar bug (with the Mageia Linux packages) here -
https://bugs.mageia.org/show_bug.cgi?id=18138 . Anyway, building llvm and then
clang from source using this bash script:

export PATH="$b/bin:$PATH"
export PKG_CONFIG_PATH="$b/lib64/pkgconfig:$b/lib/pkgconfig:$PKG_CONFIG_PATH"

And doing "make -j4 ; make -j4 check ; make -j4 install" and then running clang
from /opt/llvm on the hello world program results in an error (at least here on
Mageia Linux x86-64 v6):

shlomif at telaviv1 C/snippets/shlomif-c-snippets $ cat hello_world.c 
 * The canonical Hello World program kept here to avoid code duplication

#include <stdio.h>

int main(void)
    printf ("%s\n", "Hello World!");

    return 0;
shlomif at telaviv1 C/snippets/shlomif-c-snippets $ /opt/llvm/bin/clang
/..//bin/ld: cannot find crtbegin.o: No such file or directory

clang-3.8: error: linker command failed with exit code 1 (use -v to see

I'll attach the strace output of clang soon.
