You use libtool for creating library, so reading `info libtool Versioning'
could be helpful.

You need to adjust --version-info argument in libpcre_la_LDFLAGS. You do it by
setting EXTRA_LIBPCRE_LDFLAGS in configure.ac which expands value of
libpcre_version defined on line 17:

# Libtool shared library interface versions (current:revision:age)
m4_define(libpcre_version, [0:1:0])
m4_define(libpcreposix_version, [0:0:0])
m4_define(libpcrecpp_version, [0:0:0])

If you remove a symbol from the library, you should increase first number and
reset second and third ones to zero (change the 0:1:0 to 1:0:0 now).
And if posix anc cpp libraries are affected, then them either.

Resluting library will get different SOANAME (scanelf --soname libpcre.so) and
extension and symlinks after installation.
