tests/tools: add --as-needed to linker flags

Browse Source 
Add --as-needed to the linker flags to reduce the number of shared
library dependencies, since not all the tests and tools use all the
libraries required by the helper library (for example, many tests do not
use cairo). This helps portability of the binaries and also makes a
very small improvement to the execution speed and memory consumption.
