Makefiles: remove use of `-nostdlib` when linking shared object
Reason for its use is (was) unclear. Moreover, it causes link errors
on some systems:
/usr/lib32/libc_nonshared.a(atexit.oS): In function `atexit': (.text+0x11): undefined reference to `__dso_handle'
/usr/bin/ld: /usr/lib32/libc_nonshared.a(atexit.oS): relocation R_386_GOTOFF against undefined hidden symbol `__dso_handle' can not be used when making a shared object
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status
