I'm trying to track down a bug related the following in
gcc-configure-common.inc. I know there is one bug in the sed line, but when I
fix that I run into a second issue. I'm trying to understand what we think the
following two lines are trying to attempt:
SYSTEMLIBS_DIR=`dirname ${SYSTEMLIBS}`
[ "$SYSTEMLIBS_DIR" = "/" ] && SYSTEMLIBS_DIR=""
any ideas?
>From the commit log we expect something like:
#define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"
and we define SYSTEMLIBS_DIR in defaults.h.
so its seems if SYSTEMLIBS = 'lib', that we end up with:
#define SYSTEMLIBS ""
and thus becomes:
GLIBC_DYNAMIC_LINKER64 "ld-linux-x86-64.so.2"
which ends up being wrong.
