PATCH RFA: Fix for PR 39383 for generic ELF systems.

["Anmol P. Paralkar" <anmol at freescale dot com>]

Hello,

 Please find attached, a fix for PR 39383 in the case of generic ELF systems
 and a test-case for inclusion in the test-suite.

 Per Comment #6 in the PR, the .size assembler directive emitted ought to
 contain the "true" size of the object (when the object is of type struct
 containing a flexible array - using the size of the type is going to be
 off). The fix involves changing the definition of the ASM_DECLARE_OBJECT_NAME
 macro to use the size of the variable's initializer instead of the type of
 the variable.

 The fixed GCC was bootstrapped and tested on a PowerBook G4 (7447A altivec
 supported), running Linux 2.6.27.5-117.fc10.ppc (compared post-fix relative
 to pre-fix for each of: gcc, g++, libgomp, libmudflap, objc, gfortran, libffi,
 libjava, libstdc++ - there were no regressions - please let me know in case
 you wish to see the summaries/logs) in native configuration:
 powerpc-unknown-linux-gnu

 This is my zeroeth attempt to contribute to GCC; any advice (especially, if the
 ASM_FINISH_DECLARE_OBJECT macro needs the same change as well) is gratefully
 received.

 Thank you.

Sincerely,
Anmol P. Paralkar
