Fix commit 51a836bf

Commit 51a836bf tried to properly escape -D string defines. This change seems wrong because when quoting option like -D'SOMETHING="something"' it is not needed to escape double quotes.

If mentioned option/define is changed to -D'SOMETHING=\"something\"' it will cause build failure, because compiler will turn printf (SOMETHING); into printf (\"something\"); and will produce missing terminating " character [-Werror] error.

I want to note that this fixes compiler errors with pkg-config ≥ 0.29.1, but breaks things with pkg-config 0.29.

See pkg-config/pkg-config@1c564a35 which changed pkg-config behavior.
