STATIC build for CONFIG_FEATURE_NSLOOKUP_BIG=y cannot complated

[liwenjie119]

I build busybox for aarch64 by gcc-linaro-7.5.0, and I found that when I make with the defult "Use internal resolver code instead of libc" , it report errors as log shows; if I cancel it, it works very well.

error logs:

Static linking against glibc, can't use --gc-sections
Trying libraries: crypt m rt
Failed: -Wl,--start-group -lcrypt -lm -lrt -Wl,--end-group

new bug :
I build busybox for arm by gcc-linaro-7.5.0, but I cannot ping domains by busybox, although ping IP is ok.
