[Buildroot] [PATCH 1/1] package/libodb-mysql: don't use mysql_config outside static build

[Fabrice Fontaine]

uclibc (and glibc) installs the following ld script in
$(STAGING_DIR)/usr/lib/libc.so in addition to the 'standard' library
installed in $(STAGING_DIR)/lib:

/* GNU ld script
 * Use the shared library, but some functions are only in
 * the static library, so try that secondarily. */
OUTPUT_FORMAT("elf32-powerpc", "elf32-powerpc",
	      "elf32-powerpc")
GROUP ( /lib/libc.so.1 /usr/lib/uclibc_nonshared.a libpthread_nonshared.a AS_NEEDED ( /lib/ld-uClibc.so.1 ) )

For an unknown reason, if this script is used, this will result in
the following build failure:

configure:3286: /home/giuliobenetti/autobuild/run/instance-3/output-1/per-package/libodb-mysql/host/bin/powerpc-buildroot-linux-uclibc-gcc -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os -g0  -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  conftest.c -rdynamic -L/home/giuliobenetti/autobuild/run/instance-3/output-1/per-package/libodb-mysql/host/powerpc-buildroot-linux-uclibc/sysroot/usr/lib/mysql -lmysqlclient -L/home/giuliobenetti/autobuild/run/instance-3/output-1/per-package/oracle-mysql/host/powerpc-buildroot-linux-uclibc/sysroot/usr/lib -lz -lnsl -lm >&5

To fix this build failure, don't use mysql_config outside of static
builds.

It should be noted that this issue also affects open2300 and rsyslog
which should also be updated.
