genksyms: Handle string literals with spaces in reference files

The reference files use spaces to separate tokens, however, we must preserve spaces inside string literals. Currently the only case in the tree is struct edac_raw_error_desc in <linux/edac.h>: $ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes $ mv drivers/edac/amd64_edac.{symtypes,symref} $ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes drivers/edac/amd64_edac.c:527: warning: amd64_get_dram_hole_info: modversion changed because of changes in struct edac_raw_error_desc Signed-off-by: Michal Marek <[email protected]>
