Bug#674588: /usr/lib/llvm-3.1/bin/llvm-config: llvm-config reports bogus prefix in chroot

[Michal Suchanek]

Package: llvm-3.1
Version: 3.1-1
Severity: normal
File: /usr/lib/llvm-3.1/bin/llvm-config

Hello,

llvm-config reports some random bogus value for prefix

# llvm-config-3.1 --prefix
/

This is in a 32bit chroot.

The 64bit package and 32bit package installed outside of the chroot work
as expected.

Strace reveals
readlink("/proc/self/exe", "/usr/lib/llvm-3.1/bin/llvm-config", 4096)

Which is a no-go in the chroot.
