Add ability to serialize compilation/linking in cc rules
Specifically, both the C/C++ compiler and link rules now recognize the cc.serialize boolean variable which instructs them to compiler/link serially with regards to any other recipe. This is primarily useful when compiling large translation units or linking large binaries that require so much memory that doing that in parallel with other compilation/linking jobs is likely to summon the OOM killer. For example: obj{memory-hog}: cc.serialize = true
