postprocess-asm rule doesn't respect RUBY_EXECUTABLE

• Component: CMake
• Status: RESOLVED FIXED

[Sam James]

Originally reported downstream in Gentoo at https://bugs.gentoo.org/771744.

WebKit allows overriding the Ruby version used for the build via RUBY_EXECUTABLE using a standard
CMake mechanism and custom invocations use ${RUBY_EXECUTABLE} to ensure this is respected.

The postprocess-asm rule is a bit different from some of the others, so it's been overlooked
until now. It needs to use ${RUBY_EXECUTABLE} too, as postprocess-asm has a #!/usr/bin/env ruby
shebang that will choose the first Ruby in path.
