Subject: In the wasm makefiles, replace X:=Y with X=Y because := has different semantics depen... 
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=074b1aa42dd5b4304c3a0653de504c8b10083ef4;p=thirdparty%2Fsqlite.git

In the wasm makefiles, replace X:=Y with X=Y because := has different semantics depending on the make impl and its use is arguably a bad muscle-memory habit worth breaking. These makefiles are very specifically for GNU make, but long-term it would be nice to eliminate that requirement.
