Hmm... This is kind of strange? Why are we installing only static boost for
GLibC?

[Evgeniy Stepanov, 2011/09/27 18:38:28]

That's a historic artifact. I think everything I uploaded today and yesterday is
build only as static libraries.

I'll mass-convert them in a separate change.

[Evgeniy Stepanov, 2011/09/28 00:38:07]

I'd like to point out that DefaultConfigureStep() includes --disable-shared
flag. Also, as far as I know, libtools do not recognize that our linker is
capable of creating dynamic libraries and refuse to build one. Is there a recipe
how to fight this?
