[PATCH] libphobos: Allow building libphobos using Solaris/x86 assembler

[Iain Buclaw <ibuclaw@gdcproject.org>]

Hi,

This patch removes the disabling of libphobos when the Solaris/x86
assembler is being used.

Since r11-6373, D symbols are now compressed using back references, this
helped reduce the average symbol length by a factor of about 3, while
the longest symbol shrank from 416133 to 1142 characters.  So the issues
that were seen on Solaris/x86 should no longer be a problem.

However, I have only used x86_64-apple-darwin10 for testing, as
libphobos couldn't be built on that target for the same reason, except
it was the system linker segfaulting due to long symbol names.

It would be good to know if Solaris has also benefitted from the change.

Regards
Iain.
