Details:

The build of GNU libffcall 2.0 (which uses the libtool -export-symbols-regex
option) fails on Solaris 11.3:

/bin/sh ../libtool --mode=link gcc -m64 -O2 -o libavcall.la -rpath
/export/home/bruno/prefix64/lib -no-undefined -export-symbols-regex
'^avcall_|^__builtin_avcall$' -version-info 1:0:0 avcall.lo avcall-libapi.lo
avcall-structcpy.lo avcall-compat.lo -L/export/home/bruno/prefix64/lib
libtool: link: /usr/bin/nm -p  .libs/avcall-x86_64.o .libs/avcall-libapi.o
.libs/avcall-structcpy.o .libs/avcall-compat.o   |  | /usr/bin/gsed 's/.* //'
| sort | uniq > .libs/libavcall.exp
../libtool[1721]: eval: syntax error at line 1: `|' unexpected
*** Error code 3
make: Fatal error: Command failed for target `libavcall.la'

On Solaris 11.0 this works fine:

/bin/sh ../libtool --mode=link gcc -m64 -O2 -o libavcall.la -rpath
/home/bruno/prefix64/lib -no-undefined -export-symbols-regex
'^avcall_|^__builtin_avcall$' -version-info 1:0:0 avcall.lo avcall-libapi.lo

sed '/

libtool: link: /usr/bin/ggrep -E -e "^avcall_|^__builtin_avcall$"

libtool: link: mv -f ".libs/libavcall.expT" ".libs/libavcall.exp"
libtool: link: echo "{ global:" > .libs/libavcall.so.1.0.0.exp
libtool: link: cat .libs/libavcall.exp | /usr/bin/gsed -e "s/\(.*\)/\1;/" >>

libtool: link: (cd ".libs" && rm -f "libavcall.so" && ln -s
"libavcall.so.1.0.0" "libavcall.so")
libtool: link: ar cru .libs/libavcall.a  avcall-x86_64.o avcall-libapi.o

libtool: link: ranlib .libs/libavcall.a
libtool: link: ( cd ".libs" && rm -f "libavcall.la" && ln -s "../libavcall.la"
"libavcall.la" )

The reason for this error is that at configure time, we see

checking command to parse /usr/bin/nm -p output from gcc -m64 -O2 object...
failed

whereas on Solaris 11.0 it is

checking command to parse /usr/bin/nm -p output from gcc -m64 -O2 object...
ok

The reason for that is that the "/usr/bin/nm -p" output has slightly changed.
For the test program created by configure, it is:

conftest.o:
00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 s

00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 s 
00000000000000000000 f conftest.c
00000000000000000000 T main
00000000000000000000 T nm_test_func
00000000000000000001 C nm_test_var

whereas on Solaris 11.0 it was using 'D' instead of 'C'.

With the attached patch, configure finds that the thing works, and the build
of libffcall succeeds.
