[mixed review] Fix building ntl on Solaris with make and ld

[kiwifb]

OK so here is what got me through ntl on David's box.
The mfile patch is against the copy in the ntl patch folder
not the source. It also patch ntl spkg-install to properly
setup and tune ntl as well as cleaning the installation bits
introduced to accommodate Tim & I.
I guess Tim and I will have to fend for ourselves separately.
Also we submitted a lot of patch in the ntl style. Since
I used some GNU-ism for building shared objects most of
them will have to be revised.

Hi Francois,

Unless I am overlooking something you are removing the "-fPIC" lines from the link phase. Are you sure that will work?

Cheers,

Michael

It works all right on linux (no text relocations) but I indeed
cannot guaranty it on other platform. I just checked the gcc
manual and they recommand passing the PIC flag used during
compilation as well when using -shared so best to put it back:

-shared' Produce a shared object which can then be linked with other objects to form an executable. Not all systems support this option. For predictable results, you must also specify the same set of options that were used to generate code (-fpic', `-fPIC',
or model suboptions) when you specify this option.(1)

Looking through old tickets this is sooo obsolete. Won't fix/invalid.
