mk: fix command-line dependency check for quoted strings Before recompiling a file, rte.compile-pre.mk checks whether the command line is different from the previous one. This is done by storing for each object file the entire command line in a kind of dependency file with a .cmd extension (see obj2cmd). If that file exists, the line is retrieved first and compared against $(C_TO_O_STR). The object file gets recompiled if the file doesn't exist or if the line is different. The problem is that sometimes, files are recompiled for no apparent reason. The check doesn't work properly when a command line contains double-quoted strings such as -DFOO='"bar"' because the shell interprets and strips them. This is fixed by protecting C_TO_O_CMD with simple quotes, knowing that such quotes are already escaped in C_TO_O_STR. Moreover, because simple quotes are escaped in C_TO_O_STR, the retrieved command should be compared against C_TO_O instead.

mk: do post processing on objects that register a driver Modify the compilation makefile to identify C files that export PMD information, and use that to trigger execution of the pmdinfo binary. If the execution of pmdinfo is successful, compile the output C file to an object, and use the linker to do relocatable linking on the resultant object file into the parent object that it came from. This effectively just adds the json string into the string table of the object that defines the PMD to the outside world.

mk: fix driver build with installed SDK The tool pmdinfogen was called from RTE_OUTPUT/app/ which does not exist if building a driver outside of the SDK build. When building DPDK, RTE_SDK_BIN is RTE_OUTPUT. When building an external driver, RTE_SDK_BIN must point to the installed DPDK directory containing includes, libs, etc. That's why pmdinfogen must be installed in the SDK directory and be part of the SDK installation.
