Compiling - improve multithreaded build

In multithreaded build (at least confirmed with Windows ninja and msbuild),
at the end of "sql" target compilation, only 2 processors are used,
compiling either sql_yacc.cc or sql_yacc_ora.cc.
Thus, link of dependent executables or libraries is delayed while build is
underusing the CPU.

Rearrange the source list to improve  parallelism.
