857161 - Add flags to szip invocation on build slaves

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Mike Hommey [:glandium]]

Since bug 848770, szip has an aggressive mode for compression, where it chooses the best size for dictionary size and filter automatically, but this makes compression significantly slower, which may get in the way of developers on local builds. So, use the default compression settings by default (heh), and allow the build slave mozconfigs to set the aggressive flags.

Might want to comment that this isn't the default because it's slower and we didn't want to slow down developer builds.
