#     gen_compile_commands.py: fix path resolve with symlinks in it
#     
#     When a path contains relative symbolic links, os.path.abspath() might
#     not follow the symlinks and instead return the absolute path with just
#     the relative paths resolved, resulting in an incorrect path.
#     
#     1. Say "drivers/hdf/" has some symlinks:
#     
#         # ls -l drivers/hdf/
#         total 364
#         drwxrwxr-x 2 ...   4096 ... evdev
#         lrwxrwxrwx 1 ...     44 ... framework -> ../../../../../../drivers/hdf_core/framework
#         -rw-rw-r-- 1 ... 359010 ... hdf_macro_test.h
#         lrwxrwxrwx 1 ...     55 ... inner_api -> ../../../../../../drivers/hdf_core/interfaces/inner_api
#         lrwxrwxrwx 1 ...     53 ... khdf -> ../../../../../../drivers/hdf_core/adapter/khdf/linux
#         -rw-r--r-- 1 ...     74 ... Makefile
#         drwxrwxr-x 3 ...   4096 ... wifi
#     
#     2. One .cmd file records that:
#     
#         # head -1 ./framework/core/manager/src/.devmgr_service.o.cmd
#         cmd_drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.o := ... \
#         /path/to/src/drivers/hdf/khdf/manager/../../../../framework/core/manager/src/devmgr_service.c
#     
#     3. os.path.abspath returns "/path/to/src/framework/core/manager/src/devmgr_service.c", not correct:
#     
#         # ./scripts/clang-tools/gen_compile_commands.py
#         INFO: Could not add line from ./framework/core/manager/src/.devmgr_service.o.cmd: File \
#             /path/to/src/framework/core/manager/src/devmgr_service.c not found
#     
#     Use os.path.realpath(), which resolves the symlinks and normalizes the paths correctly.
#     
#         # cat compile_commands.json
#         ...
#         {
#           "command": ...
#           "directory": ...
#           "file": "/path/to/bla/drivers/hdf_core/framework/core/manager/src/devmgr_service.c"
#         },
#         ...
#     
#     Also fix it in parse_arguments().
