Michael Cronenworth a35f9a13a8 winegcc: Check for linker relocation support before relying on prelink. 
Prelink was used to rewrite binares and set their text segment, but
modern linkers support setting the value at link time. Prelink is
being retired by upstream.

*
* DESCRIPTION
*
* all options for gcc start with '-' and are for the most part
* single options (no parameters as separate argument).
* There are of course exceptions to this rule, so here is an
* exhaustive list of options that do take parameters (potentially)
* as a separate argument:
*
* Compiler:
* -x language
* -o filename
* -aux-info filename
*
* Preprocessor:
* -D name
* -U name
* -I dir
* -MF file
* -MT target
* -MQ target
* (all -i.* arg)
* -include file
* -imacros file
* -idirafter dir
* -iwithprefix dir
* -iwithprefixbefore dir
* -isystem dir
* -A predicate=answer
*
* Linking:
* -l library
* -Xlinker option
* -u symbol
*
* Misc:
* -b machine
* -V version
* -G num (see NOTES below)
*
* NOTES
* There is -G option for compatibility with System V that
* takes no parameters. This makes "-G num" parsing ambiguous.
* This option is synonymous to -shared, and as such we will
* not support it for now.
*
* Special interest options
*
* Assembler Option
* -Wa,option
*
* Linker Options
* object-file-name -llibrary -nostartfiles -nodefaultlibs
* -nostdlib -s -static -static-libgcc -shared -shared-libgcc
* -symbolic -Wl,option -Xlinker option -u symbol --image-base
*
* Directory Options
* -Bprefix -Idir -I- -Ldir -specs=file
*
* Target Options
* -b machine -V version
*
* Please note that the Target Options are relevant to everything:
* compiler, linker, assembler, preprocessor.
*
