Fix handling --prefix.
1 Patch to fix following test case failure:
3 === libstdc++-v3 tests ===
4 FAIL: thread/pthread1.cc (test for excess errors)
6 /opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/sh4-unknown-linux-gnu/bin/ld: cannot find -lthread
7 collect2: ld returned 1 exit status
9 Note that *any* program compiled with -pthread fails:
11 /opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/bin/sh4-unknown-linux-gnu-gcc hello.c -pthread
12 /opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/lib/gcc-lib/sh4-unknown-linux-gnu/3.3.1/../../../../sh4-unknown-linux-gnu/bin/ld: cannot find -lthread
13 collect2: ld returned 1 exit status
15 Compiling with -lpthread on the other hand works fine:
16 /opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/bin/sh4-unknown-linux-gnu-gcc hello.c -lpthread
18 So -pthread is broken in some trivial way; it should invoke -lpthread, not -lthread,
19 at least when targeting Linux.
21 http://www.sh-linux.org/rpm-2003/SRPMS/gcc-3.2.3-3.src.rpm contains a jumbo patch,
22 gcc-20030210-sh-linux-1.patch, that includes a fix for this. Here's the
23 appropriate hunk (brings in a fix for the documented -mieee option).
24 No idea if this fix is completely right, but it works for me...
