Issue: x11-plugins/purple-mm-sms-0.1.7 overwrites user's optimization (-O*).
Discovered on: amd64 (internal ref: guru_tinderbox)

NOTE:
(CLANG-STRICTER-SYSTEM) in the summary means that the bug was found on a machine that runs clang with stricter mode

This machine uses clang with CFLAGS/CXXFLAGS=-Werror=implicit-function-declaration -Werror=implicit-int -Werror=incompatible-function-pointer-types

man gcc says:
"If you use multiple -O options, with or without level numbers, the last such option is the one that is effective".

So, since the build system adds -O* after -O* provided by my CFLAGS/CXXFLAGS means that it is overwritten and unless there are known issues with -O* configured by the user, the build system should not overwrite -O*.
