clover: Introduce CLOVER_EXTRA_*_OPTIONS environment variables 

The options specified in the CLOVER_EXTRA_BUILD_OPTIONS shell
variable are appended to the options specified by the OpenCL program
in the clBuildProgram function call, if any.
Analogously, the options specified in the CLOVER_EXTRA_COMPILE_OPTIONS
and CLOVER_EXTRA_LINK_OPTIONS variables are appended to the options
specified in clCompileProgram and clLinkProgram function calls,
respectively.

v2:
 * rename to CLOVER_EXTRA_COMPILER_OPTIONS
 * use debug_get_option
 * append to linker options as well

v3: code cleanups

v4: separate CLOVER_EXTRA_LINKER_OPTIONS options

v5:
 * fix documentation typo
 * use CLOVER_EXTRA_COMPILER_OPTIONS in link stage

v6:
 * separate in CLOVER_EXTRA_{BUILD,COMPILE,LINK}_OPTIONS
 * append options in cl{Build,Compile,Link}Program
