Make poky work correctly with long TMPDIR

From: Chen Qi <[email protected]>

Poky had a problem with long TMPDIR.
If the TMPDIR had a length of 410 chars, for example, the world building would fail for three reasons.
1) autotools.bbclass: With long TMPDIR, aclocal would have a very long argument list whick makes building some packages (coretuils for example) fail.
2) qt4-native: It hardcodes some static char arrays to be 256.
3) ghostscript: It configures its MAX_TOKEN to be 256.

This series of patches are aimed at making poky building system working correctly with long TMPDIR. The three patches solve the three above problems respectively.

The following changes since commit 0d7d413d64bab8d3c758414c6c8c653ccc325653:

qt4-native: make qt4-native work with long building path
ghostscript: make ghostscript work with long building path
