libX11 configure.ac patch

[Frans Meulenbroeks]

Dear all,

While trying to compile libX11 for nios2, I discovered that configure
accidently thinks it is an os2 system (which is not the case).
The failing code is a match on target_alias for *os2*. As my
target_alias is nios2_linux, this also matches.
I found this on 1.3.2 but verified that the same code is still present
in git head.

The patch below fixes this for me, but I can imagine people prefer to
strengthen the match for os2 (not sure if changing *os2* to os2* will
work, can't really verify that).

In case further info is needed feel free to contact me directly. I am
not on the list, just someone passing by to report a problem and
solution.

Best regards & keep up the good work!
Frans
