[jdk11u-dev] RFR: 8295211: Fix autoconf 2.71 warning "AC_CHECK_HEADERS: you should use literals"

Fri Jan 13 16:13:46 UTC 2023

Please review this 11u backport fixing an issue on autoconf 2.71. It currently prints a warning on such systems. I've adjusted the code manually as the logic in that file is flipped (`=! aix` vs. `= aix` in later JDKs).

Testing: No more warning on a system that produced the warning without the patch. Warning gone with the patch. GHA.
