Tcl Source Code

Description
 This patch will correct the sequence of -pie and -shared options.
 When used together, -pie should be provided to the linker before
 -shared. If -pie is provided after -shared, the linker throws an
 error shown below as example.

-------------------------------------------------------------------------
/host/powerpc-buildroot-linux-gnu/sysroot/usr/lib/Scrt1.o:(.data+0x4):
 undefined reference to `main'
collect2: error: ld returned 1 exit status
make[2]: *** [libtcl9.0.so] Error 1
