BaseTools: Add GCC49 toolchain; align data sections to 0x40
GCC 4.9 may use 64-byte (0x40) alignment for data sections.
Therefore we use a different link script for GCC 4.9. The only
difference from the gcc4.4-ld-script is the alignment for data
sections.
When using the GCC48 toolchain with GCC 4.9, this error would be
encountered by GenFw:
> GenFw: ERROR 3000: Invalid
> Unsupported section alignment.
