like this:
$ eu-readelf -l /bin/true | grep STACK GNU_STACK 0x000000 0x00000000 0x00000000 0x000000 0x000000 RW 0x4
(replace /bin/true with the binary or library you want to check)
if it says "RW" like here, it'll have non-executable stack. If it says "RWX" or if this line is absent entirely, the stack will be executable.
