[Buildroot] [PATCH] package/expect: don't tells the linker to search for libraries in /usr/lib

[Romain Naour]

Even by using --disable-rpath option, the TCL_CC_SEARCH_FLAGS and
EXP_CC_SEARCH_FLAGS wich contains respectively "-Wl,-rpath,/usr/lib"
and "-Wl,-rpath,/usr/lib/expect5.45.3" are added to the command line:

[...]/x86_64-linux-gcc \
    -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 \
    -Os  -pipe -O2 -fomit-frame-pointer -Wall -fPIC -D_LARGEFILE_SOURCE \
    -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 \
    -Wl,--export-dynamic  \
    -o expect exp_main_exp.o \
    -L[...]/output/build/expect-2014-05-02 -lexpect5.45.3 \
    -L[...]/output/build/tcl-8.6.6/unix -ltcl8.6 \
    -ldl   \
    -Wl,-rpath,/usr/lib \
    -Wl,-rpath,/usr/lib/expect5.45.3

Remove them to avoid using host libz.so with cross-compiling.
