[Patch, avr] Set data section's LMA to AT> text instead of end of .text

[Senthil Kumar Selvaraj]

Hi,

  This patch sets the LMA for the .data section to the next available
  address in the text region (AT> text), rather than ADDR(.text) + SIZE(.text).
  This prevents address overlap errors from the linker if there are
  other sections (unknown to the default linker script) that go into the text region.

  However, I see that the MSP430 port also sets the LMA for .data by adding
  naming sections and adding section sizes. Am I missing something?

Regards
Senthil
