Missing variable 'pe_data_import_dll'

I did, and -boo- it did not work.  The I moved the definition of the
pe_get_data_import_dll_name() outside of a section of code controlled
by #ifdef DLL_SUPPORT and it worked ... :)  I have checked this
modified version in.

oops - spoke too soon - just noticed that building with
--enable-targets=all fails. I will fix this in a second...

My idea was that you create a new configure variable, eg
'targ_cflags', initialise in in configure.tgt (default empty, for
relevant targets set to '-DDLL_SUPPORT') and then process it in
configure.in and transfer it to Makefile.in via Makefile.am.... Simple
really :-)
