[PATCH v3] filter local function prefixed by $L

[Wu Zhangjin <wuzhangjin@gmail.com>]

From: Wu Zhangjin <wuzj@lemote.com>

this patch fixed the warning as following:

mipsel-linux-gnu-objcopy: 'fs/proc/.tmp_gl_devices.o': No such file
mipsel-linux-gnu-ld: fs/proc/.tmp_gl_devices.o: No such file: No such
file or directory
rm: cannot remove `fs/proc/.tmp_gl_devices.o': No such file or directory
rm: cannot remove `fs/proc/.tmp_mx_devices.o': No such file or directory

the real reason of above warning is that the $Lxx local functions will
be treated as global symbols, so, should be filtered.
