Exporters and toolchains - flags to be shared

[0xc0170]

Toolchain scripts have defined flags internal in the methods (mostly init). Therefore exporters ducplicate some but not all.

As an example for uvision (ARM) the flash size reported in the online IDE for BLE Thermometer (mkit target) is around 28k flash, exported to uvision - 48k flash.

For ARM class, in the __init__:

        main_cc = join(ARM_BIN, "armcc")
        common = ["-c",
            "--cpu=%s" % cpu, "--gnu",
            "-Otime", "--split_sections", "--apcs=interwork",
            "--brief_diagnostics", "--restrict", "--multibyte_chars"
        ]

In the uvision template, --restrict --multibyte_chars -Otime --split_sections flags are not set. This should be unified.

I imagine a toolchain class have methods: get_common_flags, get_c_flags, get_ccp_flags, and get_ld_flags.

I'll be using properties instead of getters, but the idea is the same. http://stackoverflow.com/questions/6618002/python-property-versus-getters-and-setters

#1911 is merged so this is done then? @0xc0170

This has been done a long time ago, lets get this closed out @sg-
