The max-RSS value had been bumped for several times during the 0.14.0 release cycle, showing that the current value is very close to the average RSS usage, with few redundant space.
This adds a new option to specify the RSS upper bound for compiling Zig executable file.
On AOSC OS, Zig 0.14.0 (& 0.13.0) fails to build on AArch64 and RISC-V 64, even when there are enough memory available on the build server.
I have not found a minimal repro for this, but compilation does failed when all default settings of AOSC OS were applied.
