-Expand PIC default to macho64 and respect CONFIG_PIC from libvpx

Copy PIC 'GLOBAL' macros from x86_abi_support.asm
Use .text instead of .rodata on macho to avoid broken tables in PIC mode.

-Description:
-x264/libav's framework for x86 assembly. Contains a variety of macros and
-defines that help automatically allow assembly to work cross-platform.

-Local Modifications:
-Get configuration from vpx_config.asm.
-Prefix functions with vpx by default.
-Manage name mangling (prefixing with '_') manually because 'PREFIX' does not
- exist in libvpx.
-Copy PIC 'GLOBAL' macros from x86_abi_support.asm
-Use .text instead of .rodata on macho to avoid broken tables in PIC mode.
-Use .text with no alignment for aout.

-; Macros to eliminate most code duplication between x86_32 and x86_64:
-; Currently this works only for leaf functions which load all their arguments
-; into registers at the start, and make no other use of the stack. Luckily that
-; covers most of x264's asm.
-
-; PROLOGUE:
-; %1 = number of arguments. loads them from stack if needed.
-; %2 = number of registers used. pushes callee-saved regs if needed.
-; %3 = number of xmm registers used. pushes callee-saved xmm regs if needed.
-; %4 = (optional) stack size to be allocated. The stack will be aligned before
-; allocating the specified stack size. If the required stack alignment is
-; larger than the known stack alignment the stack will be manually aligned
-; and an extra register will be allocated to hold the original stack
-; pointer (to not invalidate r0m etc.). To prevent the use of an extra
-; register as stack pointer, request a negative stack size.
-; %4+/%5+ = list of names to define to registers
-; PROLOGUE can also be invoked by adding the same options to cglobal
-
-; e.g.
-; cglobal foo, 2,3,7,0x40, dst, src, tmp
-; declares a function (foo) that automatically loads two arguments (dst and
-; src) into registers, uses one additional register (tmp) plus 7 vector
-; registers (m0-m6) and allocates 0x40 bytes of stack space.
-
-; TODO Some functions can use some args directly from the stack. If they're the
-; last args then you can just not declare them, but if they're in the middle
-; we need more flexible macro.
-
-; RET:
-; Pops anything that was pushed by PROLOGUE, and returns.
-
-; REP_RET:
-; Use this instead of RET if it's a branch target.
-
-; registers:
-; rN and rNq are the native-size register holding function argument N
-; rNd, rNw, rNb are dword, word, and byte size
-; rNh is the high 8 bits of the word size
-; rNm is the original location of arg N (a register or on the stack), dword
-; rNmp is native size
