Comparing notes: I have:

frans at linux-suse:~/oe> cat
tmp_minimal/sysroots/armv5te-oe-linux-gnueabi/usr/lib/perl/config.sh |
grep -E "^(cc=|ld=|ldflags=)"
cc="arm-oe-linux-gnueabi-gcc -march=armv5te -mtune=arm926ej-s
-mthumb-interwork -mthumb"
ld="arm-oe-linux-gnueabi-gcc -march=armv5te -mtune=arm926ej-s
-mthumb-interwork -mthumb"
ldflags="-Wl,-O1 -Wl,--hash-style=gnu"

Note the different definition of ldflags. (no -L ) and the -mthumb
versus -mno-thumb.

Btw I am using libtool 2.4 with systool support (should that matter)

Should I have this file in sysroots/armv5te....  ?
I only have
frans at linux-suse:~/oe/tmp_minimal/sysroots> find | grep heavy
./i686-linux/usr/lib/perl/5.10.1/Config_heavy.pl
./i686-linux/usr/lib/perl/5.10.1/utf8_heavy.pl
./i686-linux/usr/lib/perl/5.10.1/Config_heavy-target.pl
./i686-linux/usr/lib/perl/5.10.1/bytes_heavy.pl
./armv5te-oe-linux-gnueabi/usr/share/mysql/my-innodb-heavy-4G.cnf
./armv7a-oe-linux-gnueabi/usr/share/mysql/my-innodb-heavy-4G.cnf

And Config_heavy.pl says:
frans at linux-suse:~/oe/tmp_minimal/sysroots> grep -E
"^(cc=|ld=|ldflags=)" ./i686-linux/usr/lib/perl/5.10.1/Config_heavy.pl
cc='gcc '
ld='gcc '

-Wl,-rpath,/home/frans/oe/tmp_minimal/sysroots/i686-linux/usr/lib
-Wl,-O1 -fstack-protector -L/usr/local/lib'

Will try a compile test later.
