[PATCH] pcre: replace pcre-config with pkg-config

[Bertrand Jacquin]

Hi,

Here is fix to replace configure.in attempt to exec host pcre-config by
a pkg-config method. "Previous" method was not really adapted if you try
to cross-compile grep. If host have pcre-config, it contain host cflags
and ldflags which make linker not happy :

i586-geode-linux-uclibc-gcc  -Os -pipe -march=k6-2 -fomit-frame-pointer
-I/usr/i586-geode-linux-uclibc/usr/include/
-I/usr/i586-geode-linux-uclibc/include/    -o grep  grep.o dfa.o kwset.o
search.o grepmat.o ../lib/libgreputils.a -L/usr/lib64 -Wl,-Bstatic
-lpcre -Wl,-Bdynamic
/usr/libexec/gcc/i586-geode-linux-uclibc/ld: skipping incompatible
/usr/lib64/libpcre.a when searching for -lpcre
/usr/libexec/gcc/i586-geode-linux-uclibc/ld: cannot find -lpcre
collect2: ld returned 1 exit status
make[2]: *** [grep] Error 1

The attached patch are for grep 2.5.1a and 2.5.4.

Thanks,
Bertrand
