Subject: checkpatch: don't warn about colon termination in linker scripts

This check erroneously flags cases like the one in my recent printk
enumeration patch[0], where the spaces are syntactic, and `section:' vs. 
`section :' is syntactically important:

    ERROR: space prohibited before that ':' (ctx:WxW)
    #258: FILE: include/asm-generic/vmlinux.lds.h:314:
    +       .printk_fmts : AT(ADDR(.printk_fmts) - LOAD_OFFSET) {
