Seppo Takalo 0d6f760c16 Add minimal debug info to release and develop profiles. 
This allows minimal debugging and allows tools like
mbed-os-linker-report to work properly.

Because debugging info is kept in .elf file and not flashed to device
there is no side effects to flash sizes.

Jimmy Brisson 98b4768434 Initial toolchain class for ARMC6 
While ARMC6 does use the same linker (armlink) as ARM Compiler 5, it
is not compatible.

The reason for this incompatibility are twofold:
 * armlink may invoke the C preprocessor by adding a shebang
   (`#!`) to the top of their input files.
 * ARMC6 and ARMC5 differ in how you invoke the preprocessor:
   * ARMC5: `#! armcc -E`
   * ARMC6: `#! armclang -E`

This forces the tools to rewrite the shebang if it's wrong.

This does not yet handle dependencies properly

Tony Wu 72589dfef3 tools - turn off page alignment of sections 
By default, ld sets page alignment of sections to 0x8000, which bloats
up elf file size. This behavior is unnecessary for MCU.

Example:

1. page alignment on

mbed.elf file size 144936

Program Headers:
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  LOAD           0x008000 0x00000000 0x00000000 0x00400 0x00400 R   0x8000
  LOAD           0x008400 0x00000400 0x00000400 0x00010 0x00010 R   0x8000
  LOAD           0x008410 0x00000410 0x00000410 0x0ab3c 0x0ab3c RWE 0x8000
  LOAD           0x018000 0x20000000 0x0000af4c 0x008d0 0x008d0 RW  0x8000
  LOAD           0x01b81c 0x0000b81c 0x0000b81c 0x00000 0x00004 RW  0x8000
  LOAD           0x020000 0x1fff0000 0x1fff0000 0x00000 0x00400 RW  0x8000
  LOAD           0x0188d0 0x200008d0 0x200008d0 0x00000 0x08860 RW  0x8000

2. page alignment off

Program Headers:
