Hello,

aircrack-ng FTBFS against libgcrypt 1.11 which drops libgcrypt-config.
Since it ships an outdated copy of libgcrypt.m4 in
./build/m4/libgcrypt.m4 that cannoz handle this autoreconf does not
help.

Removing this copy lets the build continue but it later fails with:

A development snapshot of the yet-unreleased libgcrypt 1.11 is available
in experimental.
