Bug#949351: efl FTBFS: missing dependency on libx11-xcb-dev

[Helmut Grohne]

Source: efl
Version: 1.21.1-5
Severity: serious
Tags: ftbfs

efl fails to build from source, because pkg-config cannot find
x11-xcb.pc. Presumably, a dependency on libx11-xcb-dev is missing.

Also reproduced by reproducible builds:
