Patch for PR bootstrap/26872 (force use of GNU as)

[Steve Ellcey]

In the 4.1 timeframe, the GCC documentation was changed to say that GAS
is required for GCC on hppa*-*-hpux* plaltforms.  The gcc/configure.ac
script was also changed to check for gas but config.gcc was not setting
gas to yes by default.  This patch rectifies that situation.

Tested on hppa1.1-hp-hpux11.11.

OK to check in for main line and GCC 4.1 branch?
