Change default location of DJGPP's ld scripts

["Mark E." <snowball3@bigfoot.com>]

Hello again,

This patch attempts to deal with another problem brought on by the 8.3 restriction 
of filenames under plain DOS. The path generated for the default location of 
generated scripts is unusuable in a dual SFN/LFN setup like under Win 95:
c:/djgpp/i386-pc-msdosdjgpp/lib/ldscripts/

i386-pc-msdosdjgpp would turn into something like i386-pc-~.1 in plain DOS. This 
will force ld to fall back to its internal linker script.

Also, the path assumes that everyone builds their own binutils. But DJGPP users 
typically use the official port rather than rolling their own. So including the 
target alias in the path is somewhat redundant. Please consider this patch which 
deletes the target alias from the default linker script  path for DJGPP only.
