config: switch cc with libc in the config order

Some of the compiler options depend on the C library choice, (e.g.
whether core passes are needed).

Since the compiler menu comes before the C library menu, those options
may or may not be visible until the C library is chosen, leading to
either options being visible by the user (thus be puzzling as they would
not apply to his case), or invisible to him (yet again puzzling him).

Invert the order of the compiler and the C library in the menuconfig. It
anyway looks more rational, in the end.

     1 # MIPS specific options for gcc

     2 

     3 config CC_GCC_HAS_ARCH_OPTIONS

     4     default y

     5 

     6 config CC_GCC_mips_llsc

     7     tristate

     8     prompt "Use llsc"

     9     default m

    10     help

    11       This configures how gcc will emit load-link, store-conditional and

    12       sync opcodes. Normally, you'd set this to 'M', and configure will do

    13       the correct thing (ie. enable llsc for Linux-based targets, disable

    14       for others). If you know better, you can force either using llsc or

    15       not using it (resp. 'Y' or 'N').

    16 

    17 config CC_GCC_mips_synci

    18     tristate

    19     prompt "Use synci"

    20     default m

    21     help

    22       This configures how gcc will emit the synci opcode. Normally, you'd

    23       set this to 'M', and configure will do the correct thing (ie. disable).

    24       If you know better, you can force using synci (say 'Y'), or not using

    25       it (say 'N').

    26 

    27 config CC_GCC_mips_plt

    28     bool

    29     prompt "Use copy relocations & PLTs"

    30     help

    31       This configures gcc to use copy relocations & PLTs. These are

    32       extensions to the traditional SVR4-based MIPS ABIs and require

    33       support from GNU binutils and the runtime C library.

    34       Say 'N' to keep the default and not use them, say 'Y' to use them.
