[issue19391] Fix PCbuild/readme.txt in 2.7 and 3.3

[Zachary Ware]

Zachary Ware added the comment:

The 2.7 patch makes the following changes:
- python30.dll -> python27.dll
- remove "(see below)" from _bsddb and _sqlite3 which have nothing to see below
- bz2.vcproj isn't as magical as it made out to be, and it can clean itself
- nasmw -> nasm
- Remove untrue part of Building for Itanium section
- Update msdn link
- Trim trailing space

There is also a diff -w patch for 2.7, due to the large number of lines with trailing space.
