Remove -fPIC -DPIC under DJGPP

[Laurynas Biveinis]

Hello,

libtool from multi-language branch uses -fPIC -DPIC flags if libtool
is called with -prefer-pic, even if system does not support any kind
shared libraries or PIC code at all. This might be unnecessarry or 
even harmful, so I've made a patch which disables those flags for DJGPP.

Please CC on replies,
Laurynas

        * ltcf-c.sh: clear ac_cv_prog_cc_pic for DJGPP. Do not add
        '-DPIC' to ac_cv_prog_cc_pic for DJGPP.
        * ltcf-cxx.sh: likewise.
        * ltcf-gcj.sh: likewise.
        * ltconfig.sh: fix typo.
