Subject: automake: portability fixes
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f6c581cc3ef85ee1b26a02456bcbf0bf52438a23;p=librecmc%2Flibrecmc.git

automake: portability fixes

The rework of the host tools discovery caused automake to embed
absolute paths to staging_dir/host/bin/perl into the shebang
of the generated automake executables.

Switch to the portable "/usr/bin/env perl" and enable global
warnings through "$^W" instead of the "-w" interpreter argument.
