package/wolfssl: handle ARM Thumb situation

Browse Source 
By default on ARM32, wolfssl uses assembly instructions that are not
supported on Thumb (original Thumb, not Thumb 2), causing a build
failure:

/tmp/ccgn33X7.s:299: Error: selected processor does not support `umlal r4,r5,r10,ip' in Thumb mode
/tmp/ccgn33X7.s:386: Error: instruction not supported in Thumb16 mode -- `adds r4,r4,r6'
/tmp/ccgn33X7.s:387: Error: unshifted register required -- `adc r3,r3,#0'
/tmp/ccgn33X7.s:395: Error: instruction not supported in Thumb16 mode -- `adds r4,r4,r6'

Fix that by passing --with-arm-target=thumb, which tells wolfssl to
use a different set of assembly routines.
