Add option to disable/enable PIC/PIE
When attempting to import and compile the project from the TF-A
unit testing project, the linker throws some errors requiring the
code to be position-independent:
/usr/bin/ld: CMakeFiles/CppUTestExtTests.dir/MockSupport_cTestCFile.c.o:
relocation R_X86_64_32 against `.rodata.str1.1' can not be used
when making a PIE object; recompile with -fPIC
/usr/bin/ld: CMakeFiles/CppUTestExtTests.dir/OrderedTestTest_c.c.o:
relocation R_X86_64_32 against `.rodata.str1.8' can not be used
when making a PIE object; recompile with -fPIC
This is due to the fact that newer versions of the C++ compiler produce
position independent code by default, while the C compiler does not, and
therefore this leads to code incompatibility when linking.
This patch adds a flag (POSITION_INDEPENDENT_CODE) to allow the user decide
whether they want to use PIE/PIC in their code or not. Depending on the
value of the option, the project will be set up accordingly.
