Error when building libressl

Hi everyone, I'm new to LEDE. Today, I just download source and build it follow instruction. However, An error happened when it build tools/libressl, as bellow

compat/getentropy_linux.c:205:17: error: '__NR_getrandom' undeclared (first use in this function) compat/getentropy_linux.c:205:17: note: each undeclared identifier is reported only once for each function it appears in compat/getentropy_linux.c:205:42: error: 'GRND_NONBLOCK' undeclared (first use in this function)

I am using debian 7.11 and lede 17.0.1-2, Could anyone help me, pls? Thank you very much

Please try 17.01.3 instead as 17.01.1 is deprecated and not supported anymore.

Thank you very much for your reply. I did try it, but the problem still persistent
