Keep .GCC.command.line sections of LTO objetcs
This patch is for .GCC.command.line sections in LTO objects to be copied
into the final objects as in the following example:
[egeyar@localhost lto]$ gcc -flto -O3 demo.c -c -g --record-gcc-command-line
[egeyar@localhost lto]$ gcc -flto -O2 demo2.c -c -g --record-gcc-command-line -DFORTIFY=2
[egeyar@localhost lto]$ gcc demo.o demo2.o -o a.out
[egeyar@localhost lto]$ readelf -p .GCC.command.line a.out
String dump of section '.GCC.command.line':
[ 0] 10.0.1 20200227 (experimental) : gcc -flto -O3 demo.c -c -g --record-gcc-command-line
[ 56] 10.0.1 20200227 (experimental) : gcc -flto -O2 demo2.c -c -g --record-gcc-command-line -DFORTIFY=2
2020-03-05 Egeyar Bagcioglu <egeyar.bagcioglu@oracle.com>
* simple-object.c (handle_lto_debug_sections): Name

from lto objects.
