configure: avoid broken bashisms #243

Closed eli-schwartz closed 9 months ago

eli-schwartz commented 9 months ago

configure scripts are run with /bin/sh, and must use /bin/sh syntax rather than bashisms.

<<< is a bash specific syntax. Refrain from using it. Instead simply echo into a pipe, which does the same thing.

Fixes the following error:

checking for XML2... yes
checking for libxml2... yes; used pkg-config
./configure: 31971: Syntax error: redirection unexpected
