yann@1: complibs: add option to use distro-provided libs
yann@1: 
yann@1: Now that some distros are catching up (eg. Debian testing at least),
yann@1: add an option to use companion libs from the distro.

yann@1: +      Most of the distributions current as of this writing lack the proper
yann@1: +      version of the required companion libraries, or do not even package
yann@1: +      those.  For example Debian Lenny has too old a version for PPL, and
yann@1: +      does not provide MPC and CLooG.
yann@1: +      
yann@1: +      But now distributions are catching up, and some (most?) of them do
yann@1: +      package the proper versions of those libraries. For example again,
yann@1: +      Debian Squeeze (still in testing) has the proper versions now.
yann@1: +      
yann@1: +      If you want to trust your distribution for providing the companion
yann@1: +      libraries, say 'Y' here, or if you want crosstool-NG to build them
yann@1: +      for you, say 'N'.
yann@1: +      
yann@1: +      The default is 'N', to cope with stable productions systems that most
yann@1: +      probably are using proven-stable distributions, and can not upgrade.
yann@1: +      
yann@1: +      Also, this is still experimental, so you'd better say 'N' if you are
yann@1: +      not sure.
yann@1: +      
yann@1: +      Note-1: if you say 'Y' here, it is very probable that the libraries
yann@1: +      will be linked in dynamically, and not static. This is not an issue
yann@1: +      if you keep the toolchain on the machine where it was built, but can
yann@1: +      become one if you want to move the toolchain to another machine, with
yann@1: +      an older distro. You've been warned!
yann@1: +      
yann@1: +      Note-2: for now, this is an all-from-distro or all-from-crosstool-NG
yann@1: +      setting. You can't use one lib from the distro, and build another
yann@1: +      one from crosstool-NG.
