[OE-core] [PATCH 1/1] glib-2.0: fix a host contamination issue

[Robert Yang]

We will see the following warning by accident:

$ bitbake nativesdk-glib-2.0

WARNING: QA Issue: nativesdk-glib-2.0-dbg: found library in wrong location:
/opt/poky/0.5.5/sysroots/x86_64-pokysdk-linux/usr/share/gdb/auto-load/opt/
poky/0.5.5/sysroots/x86_64-pokysdk-linux/usr/lib/libglib-2.0.so.0.3600.4-gdb.py

There are two '/opt/poky/0.5.5/sysroots' in the path when the warning
comes, this is what we need since glib-2.0 has done this intentionally
in its configure and Makefile.

This is because the configure script uses the:
ABS_GLIB_RUNTIME_LIBDIR = "readlink -f $libdir/$with_runtime_libdir`"
to figure out the abs dir, so if
/opt/poky/0.5.5/sysroots/x86_64-pokysdk-linux/usr/lib/ exists , there
would be warning, otherwise no warning.

We can change the "readlink -f" to "readlink -m" to fix the host
contamination issue.

Another fix could be:
ABS_GLIB_RUNTIME_LIBDIR =""

But this is much more like a workaround.

BTW, fix the previous sed command's indent.
