# @@CONFIG_TARGET_TRIPLE@@-ld: Solo5 wrapper for 'ld'.
# Generated by configure.sh at build time.
#
# Passes through to @@CONFIG_TARGET_LD@ for actual work. Defines all flags
# required for correct operation when linking code intended for inclusion in a
# Solo5 unikernel.
#
# Provides a '-z solo5-abi=ABI' option to select the Solo5 bindings to use if
# linking a unikernel. No default for ABI is provided, as it is expected that a
# caller directly using 'ld' knows what they are doing.
