[Patch] Fix gcc.dg/20050922-*.c

[Vidya Praveen]

Hello,

Tests gcc.dg/20050922-1.c and gcc.dg/20050922-2.c includes stdlib.h. This can
be a issue especially since they define uint32_t. Testcase writing guidelines
discourages such inclusion as well.

This patch replaces these #includes with manual declarations.

Tested for aarch64-none-elf, arm-none-eabi and x86_64-linux-gnu

OK for trunk, 4.7, 4.8?

VP.
