[patch] translate dashes in filenames for headers install

[patch] translate dashes in filenames for headers install

[Mike Frysinger]

[-- Attachment #1.1: Type: text/plain, Size: 283 bytes --]

the current filename->define translation does not scrub dashes so when 
creating stub defines for like asm-x86_64/ptrace-abi.h, we get:
#define __ASM_STUB_PTRACE-ABI_H

gcc just hates that sort of thing :)

trivial attached patch adds - to the tr list to scrub it to _

Make sure we translate dashes in file names to underscores for use as defines.
