bug#27509: PGI compiler detection in libtool.m4

[Dong, Min]

Hi,

 

PGI compiler since 2017 has changed their default version output.

 

Before 2017:

$ pgcc -V

 

pgcc 16.9-0 64-bit target on x86-64 Linux -tp sandybridge

After 2017:

$ pgcc -V

 

pgcc 17.5-0 64-bit target on x86-64 Linux -tp sandybridge

This caused configure script unable to detect compiler correctly, when it is in a wrapper such as mpicc.
