XL compiler name in Cell

[Roger Ferrer Ibáñez]

Hi,

although XL is currently supported by the latest release of libtool, 
IBM's Cell toolchain preprends the name of the compiler with 'ppu' 
(standing for PPU, Power Processing Unit of the CBE Architecture). 
Compilers are thus called 'ppuxlc', 'ppuxlC' and 'ppuxlf' (the latest 
one for Fortran). Out of the box libtool does not recognize these 
compilers as XL and does not pass the proper flags to generate dynamic 
libraries.

Attached there is a minor patch to support 'ppuxl[cC]' and 'ppuxlf', 
besides plain 'xl[cC]' and 'xlf'. We initially considered something like 
'*xl[cC]' and '*xlf' but we think it is a bit crude (and 'spuxlc', which 
does not support dynamic libraries would be incorrectly guessed as doing 
so).

On the other hand, I wonder whether there is a way to tell libtool that 
the found compiler can be handled like another known to libtool, without 
having to resort on strategically named soft links or shell scripts.

Thanks a lot,
