Configure shell failure (nexted quotes, find_pcre.m4) in 2.7.1

[rainerjung]

Version 2.7.1 produces a shell error trying to execute "cut" due to incorrectly nested quotes introduced in commit 0757a9f.

Problematic line inbuild/find_pcre.m4 is:

PCRE_LD_PATH="/${PCRE_CONFIG} --libs | cut -d"/" -f2,3,4,5,6 | cut -d " " -f1"

Correct would be:

PCRE_LD_PATH="/${PCRE_CONFIG} --libs | cut -d'/' -f2,3,4,5,6 | cut -d ' ' -f1"

(Change from >"< to >'< when quoting the cut delimiters.

Otherwise the quotes around the single space are actually terminating the backquote and the shell tries to execute the command "-f1".

Fixed. Thanks!
