Subject: [PATCH] package/docopt-cpp: fix static build

Fix the following static build failure raised since the addition of the
package in commit 43f96ced67c9a1f84d3f0edf5cd632178eb176b8:

[ 66%] Linking CXX shared library libdocopt.so
ld (ld-elf2flt): -shared used without passing a shared library ID

Fixes:
