glibc: configure adding debug symbols in glibc build
After building the cross toolchain and compile a simple C program,
objdump reports debug information even though -g modifier was not
used. These debug segments are in glibc library and CRT files. So
a new config entry: CT_GLIBC_ENABLE_DEBUG was added to control when
we want to add debug information to glibc, by default is enabled.
