Turns out the culprit is libportsmf-dev, which installs a pkg-config file

  /usr/lib/pkgconfig/portSMF.pc

which includes some compiler flags in its Cflags that no pkg-config
file normally has business of including, hence causing packages using
it to be always compiled with -g -O2 -Wall:

------------------------------------------------------------
$ grep Cflags /usr/lib/pkgconfig/portSMF.pc 
Cflags: -I${includedir}/portSMF -g -O2  -Wall
------------------------------------------------------------
