[LTP] [PATCH] nm01: Remove prefix zeros of the addresses output by nm before comparing

[zhe.he]

From: He Zhe <zhe.he@windriver.com>

The latest nm v2.33.1.20191208 outputs symbols addresses without prefix zeros
for "nm -f posix", which causes the following error.
nm01 5 TFAIL: Got wrong format with -f bsd

Let's remove the prefix zeros before comparing.

AWK is base on stream editing, maybe we need the output to a new log file.

The regex is not fit for nm_posix.out since this format of address does not
start with 0000000000, e.g.

# cat nm_posix.out | grep 40108f
.annobin_init.c t 40108f
.annobin_init.c_end t 40108f

# echo 40108f | awk '{print gensub(/(0+)([0-9a-fA-F]+)/, "\\2", "g")}'
4108f

Thanks for pointing it out. I'll send v2.
