ghs: fix the gnu-elf.ld handle error at pre-process

Browse source 
In Green Hills, if the name of the file to be preprocessed ends with ".ld",
this file must be renamed to ".ld.i". Otherwise, the following error will be reported:

ccarm: Error: -o out/build/cmake_out/mann_dcu_evb_ghs_ap/gnu-elf.ld has wrong suffix for -P option (expect .i)

Currently, based on the documentation and actual operations, only files
ending with "*.ld" can trigger this preprocessing error. There are no such
issues in other cases.
