RFR: JDK-8140484: Vardeps broken when variable value contains '$'

[Magnus Ihse Bursie]

The fix looks good. I'm just wondering if there are any other problematic characters that needs to be escaped, such as \. Or should we address such issues when they arise?

By reading the old value as a makefile using "include", variable substitution is applied. To work around this, dollar characters need to be escaped (doubled) prior to printing the variable value to the vardeps makefile.
