WITHOUT_PROFILE=yes by default

[Max Khon]

Hello!

Are there any compelling reasons for having profiled libs to be built by
default?
They are of no use for 100% users and 99,999% developers and just slow down
world and universe builds.

Here are the results of running buildworld on 1 core on AMD Athlon(tm) 64
X2 Dual Core Processor 4400+:
make buildworld
     8265,06 real      6400,27 user      1059,2 sys
make buildworld (WITHOUT_PROFILE=yes)
     7840,05 real      5379,13 user       904,61 sys

I would like to disable building profiled libraries by default. Opinions?
