Benoît Thébaudeau" f173e77e32 complibs/cloog: fix linking with libm 
In Ubuntu 11.04 and 11.10, the default options for ld have changed.
--no-copy-dt-needed-entries and --as-needed are now enabled by default, which
causes errors like:

[EXTRA]    Checking CLooG/ppl
[DEBUG]    ==> Executing: 'make' '-j3' '-s' 'check'

[ALL  ]    config.status: creating include/cloog/cloog-config.h

 it to the linker command line

[ERROR]    make[2]: *** [cloog] Error 1
[ERROR]    make[1]: *** [check-recursive] Error 1

See:
https://wiki.ubuntu.com/NattyNarwhal/ToolchainTransition

This patch fixes these errors by placing '-lm' at the right place on the command
line as libppl requires libm when linking cloog.

README 

This is the README for crosstool-NG

Crosstool-NG follows the autoconf dance. So, to get you
kick-started, just run:
    ./configure --help

If you are using a development snapshot, you'll have to
create the configure script, first. Just run:
    ./bootstrap

You will find the documentation in the directory 'docs'.
Here is a quick overview of what you'll find there:
  0 - Table of content
  1 - Introduction
  2 - Installing crosstool-NG
  3 - Configuring a toolchain
  4 - Building the toolchain
  5 - Using the toolchain
  6 - Toolchain types
  7 - Contributing
  8 - Internals
  A - Credits
  B - Known issues
  C - Misc. tutorials
